Description

Technical Field

[0001] This invention relates to the field of rubber sleeve extruder technology, specifically to a material cutting and feeding structure for use after extrusion in a rubber sleeve extruder. Background Technology

[0002] The rubber sleeve extruder heats, shears, and mixes the rubber compound through a screw system, transforming the solid compound into a uniform and plastic molten state. The molten compound is then extruded through a die head into a continuous tubular structure. This process directly determines the initial shape, dimensional accuracy, and density of the sleeve. The rubber sleeve extruder is not only the core equipment for molding, but also ensures the product quality and process adaptability of the sleeve through functions such as plasticization control, impurity filtration, and multi-layer co-extrusion.

[0003] When processing rubber sleeve extruders, the extruded rubber material needs to be cut manually, which results in low collection efficiency. Furthermore, after cutting, the material needs to be manually aligned, making it inconvenient to cut and arrange the processed material using rubber sleeve extruders. Summary of the Invention

A limiting spring is connected between the two limiting rods.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The rubber sleeve extruder uses a cutting and feeding structure after extrusion. After extrusion, the extruded material can be guided by the drive assembly and guide rods. After positioning and measurement by an infrared sensor, the extruded material can be cut by activating the cutting assembly. Simultaneously, the drive motor can be started, causing the first rotating rod to rotate the feeding rod via the sleeve rod. This allows the feeding rod to rotate within the spacing of the guide rods, thereby pushing the cut rubber material to one side. When the moving rod rotates, it can rotate the large gear set on the surface, so that the large gear can rotate the first rotating rod through the small gear, so that the first rotating rod can rotate the second rotating rod through the first synchronous belt, so that the second rotating rod can rotate the rotating gear, and the rotating gear can move the connecting rod and the connecting block through the toothed plate and the cross bar. In this way, the collection groove opened inside the receiving plate can collect the pushed-out rubber material and ensure that the pushed-out material enters the displacement collection groove. In combination with the use of the cutting component, it can not only have a good cutting effect but also a good material placement effect.

[0018] 2. The material cutting and unloading structure used after extrusion in this rubber sleeve extruder ensures good movement of the rubber material through the use of the drive assembly. The drive assembly rotates the connected second rotating rod, which in turn rotates the first connecting rod via the first bevel gear set. The first connecting rod then rotates the synchronizing rod via the second pulley set, which in turn rotates the second connecting rod via the second bevel gear set. The second connecting rod then rotates the second gear via the first gear, which is evenly distributed and meshed. This rotation of the second gear rotates the internally installed drive rod, which in turn rotates the connected fan blades. The rotating fan blades cool the displaced rubber material, preventing bending during movement and achieving a better cooling effect.

[0019] 3. The material cutting and feeding structure used after extrusion in this rubber sleeve extruder: When the rubber sleeve extruder is in use, the rubber material can be cut by the cutting component, and the cutting component can be cleaned by the cleaning scrapers set on both sides. Since the cutting component needs to move continuously, it can push the cleaning scraper during movement, so that the cleaning scraper can move. And through the reset of the spring displacement block, it can be ensured that the cleaning scraper can continue to fit the cutting component during movement, thereby avoiding loss of cleaning effect during movement, and thus avoiding interference during material cutting.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 The present invention provides a technical solution: a material cutting and feeding structure for use after extrusion of a rubber sleeve extruder, including an extruder body 1, a feed port 2 opened at the top of the extruder body 1 and a control panel 3 installed at one end of the extruder body 1, a receiving frame 4 is provided on one side of the extruder body 1, a receiving frame 5 for receiving materials is provided at the top of the receiving frame 4, a driving component 6 is provided inside the receiving frame 5, and a cutting component 7 for cutting materials is installed at the top of the receiving frame 5.

[0032] A receiving plate 8 for receiving material is provided at the end of the receiving frame 5 away from the cutting component 7 and between it and the extruder body 1. A collecting component for discharging material is provided on one side of the extruder body 1. The collecting component includes a protective frame 9 provided on one side of the receiving frame 5 and welded to it by a vertical rod. A drive motor 10 is installed on one side of the protective frame 9. The output end of the drive motor 10 is connected to a first rotating rod 11 through a coupling. A sleeve rod 12 is provided on the surface of the first rotating rod 11. A discharge rod 13 for unloading material is provided on the surface of the sleeve rod 12. The discharge rod 13 is evenly distributed on the surface of the sleeve rod 12. A moving component is provided inside the protective frame 9 at the end near the first rotating rod 11.

[0033] This invention relates to a material cutting and feeding structure for use after extrusion in a rubber sleeve extruder. The extruder body 1 has three output ports, enabling simultaneous discharge from the three outlets and increasing the discharge rate. The feed rods 13 are in a group of three, each with a different length and progressively increasing in length, so that they can progressively push the rubber material placed in different areas during rotation. Furthermore, an infrared sensor is installed at the top of the receiving rack 4, which allows for the limitation of the length of the rubber material.

[0034] exist Figure 4 and Figure 5 In the moving component, there are a large gear 14 disposed on the surface of the first rotating rod 11, a first rotating rod 15 disposed at one end of the large gear 14 and connected to the inside of the protective frame 9 by a bearing, a small gear 16 disposed on the surface of the first rotating rod 15 and matched with the large gear 14, a second rotating rod 17 disposed at the end of the first rotating rod 15 away from the first rotating rod 11 and connected by a bearing, a rotating gear 18 disposed on the surface of the second rotating rod 17, a first synchronous belt 19 connecting the second rotating rod 17 and the first rotating rod 15, and a toothed plate 20 meshing with one end of the rotating gear 18.

[0035] This is a material cutting and unloading structure used after extrusion in a rubber sleeve extruder. The gear ratio between the large gear 14 and the small gear 16 is 3:1, so that when the large gear 14 rotates once, the small gear 16 rotates three times. At the same time, the first synchronous belt 19 is equipped with a rack, so that the first rotating rod 15 and the second rotating rod 17 can rotate synchronously during rotation.

[0036] After extrusion, the rubber sleeve extruder can guide the extruded material through the drive assembly 6 and guide it via a guide rod. After positioning and measurement by an infrared sensor, the extruded material is cut by activating the cutting assembly 7. Simultaneously, the drive motor 10 is activated, causing the first rotating rod 11 connected to its output end to rotate. This rotation of the first rotating rod 11 causes the sleeve rod 12 connected to its surface to rotate, which in turn causes the feeding rod 13 to rotate within the spacing of the guide rods. This pushes the cut rubber material to one side. The rotation of the first rotating rod 11 also causes the large gear 14 on its surface to rotate, which in turn causes the small gear 16 meshing with it to rotate. When in motion, the first rotating rod 15 can rotate, which in turn rotates the second rotating rod 17 via the first synchronous belt 19. This, in turn, rotates the rotating gear 18. Since the gear ratio of the large gear 14 to the small gear 16 is 3:1, when the sleeve rod 12 rotates once, the small gear 16 and the rotating gear 18 rotate three times. This rotation of the rotating gear 18 moves the toothed plate 20, which in turn moves the connecting rod 22 and the connecting block 23 via the crossbar 21. This, in turn, moves the receiving plate 8 connected at the top, displacing it by the distance the rotating gear 18 rotates three times. This allows the collection groove inside the receiving plate 8 to collect the ejected rubber material, ensuring that the ejected material enters the displaced collection groove. Combined with the use of the cutting component 7, this results in not only a better cutting effect but also a better material placement effect.

[0037] exist Figure 1 and Figure 6 In the middle, a crossbar 21 is welded to one side of the toothed plate 20, and a connecting rod 22 is slidably connected to the other end of the crossbar 21 on the surface of the receiving frame 4. Both ends of the connecting rod 22 are provided with connecting blocks 23, and the connecting blocks 23 are symmetrically distributed on the surface of the receiving frame 4. The top of the connecting block 23 is provided with a positioning block 24 for snapping. The drive assembly 6 includes a starter motor installed on one side of the receiving frame 5. The output end of the starter motor is connected to a positioning rod. The receiving frame 5 is provided with evenly distributed guide rods on the side near the positioning rod.

[0038] This is a material cutting and feeding structure used after extrusion in a rubber sleeve extruder. The connecting blocks 23 are symmetrically distributed on the surface of the receiving frame 4, so that the receiving plate 8 can be relatively stable when it moves.

[0039] exist Figure 7In the process, a synchronous rotation component is provided at one end of the receiving frame 5. The synchronous rotation component includes a second rotating rod 25 provided at one end of the drive component 6. A first connecting rod 26 connected to the second rotating rod 25 is provided at the end of the receiving frame 5 near the second rotating rod 25 via a bearing. A first bevel gear set 27 is connected between the first connecting rod 26 and the second rotating rod 25. A synchronous rod 28 is provided at one end of the first connecting rod 26. A second pulley set 29 is connected between the synchronous rod 28 and the first connecting rod 26. A heat dissipation and cooling component is provided on the side of the receiving frame 5 away from the synchronous rotation component. The heat dissipation and cooling component includes a second connecting rod 30 connected to the receiving frame 5 via a bearing. A second bevel gear set 31 is connected between the second connecting rod 30 and the synchronous rod 28. A first gear 32 is provided on the surface of the second connecting rod 30. A second gear 33 is meshed with one side of the first gear 32. A drive rod 34 connected to the second gear 33 via a bearing is provided at one end of the second gear 33. A fan blade 35 is provided on the surface of the drive rod 34.

[0040] This is a material cutting and unloading structure for use after extrusion in a rubber sleeve extruder. Because the second gears 33 are meshed, the internal drive rod 34 can rotate in the opposite direction when rotating. At the same time, the fan blades 35 are staggered and rotate in opposite directions, which avoids increasing the blowing effect during blowing, thereby improving the cooling effect.

[0041] When the rubber sleeve extruder is in use, the drive assembly 6 ensures good movement of the rubber material. The drive assembly 6 rotates the connected second rotating rod 25, which in turn rotates the connected first bevel gear set 27. The first bevel gear set 27 then rotates the connected first connecting rod 26, which in turn rotates the second pulley set 29, which in turn rotates the synchronizing rod 28. The synchronizing rod 28 then rotates the second bevel gear set 31, causing the second bevel gear set 31 to rotate. When rotating, the second connecting rod 30 can rotate, which in turn rotates the first gear 32. The first gear 32, when rotating, can rotate the meshing second gear 33. The second gear 33 is evenly distributed and meshing, so that when the second gear 33 rotates, it can rotate the internally installed drive rod 34. The drive rod 34, when rotating, can rotate the connected fan blade 35. Thus, when the fan blade 35 rotates, it can cool the displaced rubber material, thereby preventing bending during movement and achieving a better cooling effect.

[0042] exist Figure 8In the process, the cutting assembly 7 includes a cutting frame disposed at the top of the receiving frame 5, and symmetrically distributed electric push rods are installed inside the cutting frame. The bottom end of the electric push rod is connected to a cutting tool. A cleaning assembly is disposed at the bottom of the cutting assembly 7. The cleaning assembly includes a cleaning scraper 36 disposed at the bottom of the cutting frame, and the cleaning scraper 36 is symmetrically distributed at the bottom of the cutting frame. A spring displacement block 37 for sliding between the cleaning scraper 36 and the cutting frame is disposed at the top of the cleaning scraper 36. A welded plug-in block 38 is disposed at the end of the cleaning scraper 36 near the spring displacement block 37.

[0043] This is a material cutting and unloading structure used after extrusion in a rubber sleeve extruder. The cleaning scrapers 36 are symmetrically distributed at the bottom of the cutting frame, so that both sides of the cutting component 7 can be cleaned simultaneously.

[0044] exist Figure 9 In the middle, a locking assembly is provided at one end of the cleaning scraper 36 near the plug block 38. The locking assembly includes a fixing frame 39 provided at the top of the cleaning scraper 36. A limiting rod 40 for locking is provided inside the fixing frame 39, and the limiting rods 40 are symmetrically distributed inside the fixing frame 39. A limiting spring 41 is connected between the two limiting rods 40.

[0045] This is a material cutting and unloading structure used after extrusion in a rubber sleeve extruder. By setting a limiting spring 41, it can be reset after the limiting rod 40 is released, thereby driving it to move back to its original position.

[0046] When the rubber sleeve extruder is in use, the rubber material can be cut by the cutting component 7, and then the cleaning scrapers 36 set on both sides can be used to clean the cutting component 7. Since the cutting component 7 needs to move continuously, it can push the cleaning scrapers 36 during movement, so that the cleaning scrapers 36 can move. And through the reset of the spring displacement block 37, it can be ensured that the cleaning scrapers 36 can continue to adhere to the cutting component 7 during movement, thereby avoiding loss of cleaning effect during movement. At the same time, the two limiting rods 40 can be pulled, so that the limiting rods 40 can squeeze the limiting spring 41 set on one side during movement. After the limiting rods 40 move, they can separate from the insertion block 38. Then, the cleaning scraper 36 can be pulled, so that the cleaning scraper 36 can drive the insertion block 38 to move out at the bottom of the spring displacement block 37, thereby facilitating the cleaning of the cleaning scraper 36 and avoiding interference during material cutting.

[0047] In summary, the rubber sleeve extruder heats, shears, and mixes the rubber compound through a screw system, transforming the solid rubber compound into a uniform and plastic molten state. Because the extruder body 1 has three extrusion ports, it can simultaneously extrude three groups of rubber materials, thereby improving the extrusion effect. Furthermore, the cutting component 7 can cut the guided rubber material. Simultaneously, starting the drive motor 10 causes the feed rod 13 to rotate, pushing the cut material for rapid feeding. The movement of the toothed plate 20 causes the receiving plate 8 to move synchronously, collecting the fed rubber material and placing it into the designated slot. This results in both good cutting and material placement effects. Content not described in detail in this specification is prior art known to those skilled in the art.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
