Description

Technical Field

[0001] The present invention relates to the technical field of composite material production, and specifically to a balanced extrusion system for hydrolysis-resistant nylon-based composite materials. Background Art

[0002] Nylon, also known as polyamide fiber, has good comprehensive properties and is widely used in various aspects of life. In polyamide-based composite materials, the affinity between nylon and glass fiber is very good. Fiber reinforcement can reduce the water absorption rate of the resin, enabling it to work under high temperature and high humidity. Nylon-based composite materials are formed by mixing nylon resin pellets and glass fiber pellets in a certain proportion and then feeding them into the hopper of an extruder. The extruder melts and blends the pellets and then extrudes them. The extrusion temperature is a key factor affecting the melting and flow properties of plastics. Selecting an appropriate extrusion temperature can ensure the stability of the shape, size, and performance of the extrudate.

[0003] For example, in the Chinese patent with the publication number CN209095947U and the name "Production Equipment for Glass Fiber Reinforced Hydrolysis-Resistant Polyamide Composite Materials", it includes a feeding barrel, a machine body, a feeding motor, and a mold. The feeding barrel is arranged above the middle of the machine body. The feeding motor is arranged on one side of the feeding barrel and fixedly bolted to the outer surface of the machine body. A feeding port is opened at the connection between the bottom end of the feeding barrel and the machine body. One end of the machine body is fixedly connected with an extrusion head, and the top end of the extrusion head is directly opposite to the feeding port opened on the mold. A mold cavity is opened in the mold, and the interior of the machine body is hollowed out to form a barrel cavity. An extrusion rod is arranged through the barrel cavity. This kind of utility model is reasonably designed and easy to use. By using the method of twin-screw co-mixing and extrusion, nylon 66 (PA66), glass fiber, hydrolysis-resistant agent, etc. can be compounded to prepare a material with good rigidity, impact toughness, and excellent hydrolysis resistance at the same time. This material can be directly injection-molded, and the production efficiency is high.

[0004] Although the production equipment for glass fiber reinforced hydrolysis-resistant polyamide composite materials in the above patent is practical and convenient, it also has deficiencies. Generally, a section of the hose just extruded is dragged by workers using tools, passed through a water tank and guide rollers, and moved to a winding roll. And the dragged section of the hose is usually deformed, and this section of waste hose needs to be cut off and centrally recycled. The recycled plastic pipe can be processed secondary to reduce the waste pipe rate. After winding, the hose at the extruder end also needs to be cut to facilitate the subsequent bundling of the hose on the winding roll. Summary of the Invention

Then, the clamping jaws first move to between the winding roller and the extruder. After winding is completed, the clamping jaws move towards the extruder, and the nylon plastic pipe at the extruder end is cut through the second linkage assembly, which is convenient for subsequent bundling of the nylon plastic pipe on the winding roller.

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0028] Please refer to Figure 1-10, a technical solution provided by an embodiment of the present invention: The hydrolysis-resistant nylon-based composite material balanced extrusion system includes a processing table 1, an extruder 2 arranged on the processing table 1, a transmission assembly, a first linkage assembly, and a second linkage assembly. A moving block 42 is horizontally slidably connected to the processing table 1. A clamping jaw 4 for clamping a nylon plastic pipe is arranged inside the moving block 42. A winding roller 7 is arranged inside the processing table 1. A pressing rod 30 is vertically slidably connected to the processing table 1, and the pressing rod 30 is located above the winding roller 7. A cutting knife 11 is rotatably connected to one side of the moving block 42 facing the extruder 2. The transmission assembly receives the drive of the horizontal sliding of the moving block 42 to vertically move the pressing rod 30 downward. The pressing rod 30 fixes the nylon plastic pipe on the winding roller 7. The first linkage assembly receives the drive of the downward movement of the pressing rod 30 to rotate the cutting knife 11. The second linkage assembly receives the drive of the horizontal sliding of the moving block 42 towards the extruder 2 to rotate the cutting knife 11 in the reverse direction. Specifically, a water tank 5 is opened on the processing table 1 for cooling the nylon plastic pipe to quickly shape it and maintain the required shape and size. A blower 3 is also arranged on the processing table 1. The blower 3 is a heating and cooling blower 3. The outlet of the blower 3 is directly facing the outlet of the extruder 2. When the extrusion temperature is too high, the blower 3 can cool the outlet to avoid the oxidation and decomposition of the base material, resulting in poor mechanical properties of the material. When the extrusion temperature is too low, the blower 3 can heat the outlet to improve the coating effect of the glass fiber.

[0029] As a preferred technical solution, the transmission assembly includes a pushing block 41, an abutting block 28, and an inserting rod 29. A connecting block 40 is arranged on the processing table 1. The inserting rod 29 is horizontally slidably connected inside the connecting block 40 through an elastic member. The pressing rod 30 is vertically slidably connected to the connecting block 40. The bottom of the inserting rod 29 is fixedly connected to the abutting block 28. A jack 31 is opened on the pressing rod 30. The inserting rod 29 is inserted and matched with the pressing rod 30 through the jack 31. One end of the inserting rod 29 facing the pressing rod 30 is inclined. The pushing block 41 is arranged on the top of the moving block 42. The pushing block 41 is in abutting cooperation with the abutting block 28. Specifically, the pressing rod 30 is horizontally placed inside the connecting block 40 in the initial state. When the moving block 42 moves horizontally, the pushing block 41 abuts against the abutting block 28. The pushing block 41 drives the abutting block 28 to horizontally move away from the extruder 2. The inserting rod 29 disengages from the jack 31 on the pressing rod 30. The pressing rod 30 moves downward towards the winding roller 7. By clamping with the winding roller 7, this section of the nylon plastic pipe is fixed on the winding roller 7, improving personal safety, reducing risks such as pinching and the rebound of the nylon plastic pipe, facilitating subsequent winding and collection, and improving work efficiency.

[0030] As a preferred technical solution, the elastic member includes a third guide rod 38 and a second spring 37 sleeved on the third guide rod 38. A third chute 36 is horizontally formed in the connecting block 40. The third guide rod 38 is horizontally arranged in the third chute 36. The inserting rod 29 is slidably sleeved on the third guide rod 38. Two ends of the second spring 37 are respectively fixedly connected to the inserting rod 29 and the bottom wall of the third chute 36. Specifically, when the moving block 42 drives the pushing block 41 to move in the reverse direction, the inserting rod 29 and the abutting block 28 are driven by the second spring 37 to horizontally move toward the direction of the extruder 2. And during the process that the roller 7 continuously winds the nylon plastic pipe, as the number of winding turns of the nylon plastic pipe increases, the pressing rod 30 continuously moves upward. When the top of the pressing rod 30 abuts against the inclined surface of the inserting rod 29, the pressing rod 30 continues to move upward, pushing the inserting rod 29 to move away from the extruder 2. When the pressing rod 30 moves upward again and the inserting hole 31 is at the same horizontal height as the inserting rod 29, the second spring 37 drives the inserting rod 29 to be inserted into the inserting hole 31, completing the reset of the pressing rod 30. At this time, the winding stops, facilitating the fixation of the next section of the nylon plastic pipe.

[0031] As a preferred technical solution, a second chute 39 is vertically formed in the processing table 1. A second guide rod 34 is vertically arranged in the second chute 39. A first spring 35 is sleeved on the second guide rod 34. The pressing rod 30 is vertically slidably sleeved on the second guide rod 34. Two ends of the first spring 35 are respectively fixedly connected to the bottom of the pressing rod 30 and the bottom wall of the second chute 39. Specifically, the second guide rod 34 plays a limiting role, enabling the pressing rod 30 to only move vertically in a straight line without any horizontal position offset. When the inserting rod 29 disengages from the inserting hole 31 on the pressing rod 30, under the combined action of the self-weight of the pressing rod 30 and the first spring 35, the pressing rod 30 moves downward toward the roller 7, fixing this section of the nylon plastic pipe on the roller 7 and being able to adapt to the change in the winding thickness of the nylon plastic pipe during the winding process, ensuring that the nylon plastic pipe will not loosen or fall off during the winding process.

[0032] As a preferred technical solution, the first linkage assembly includes a first gear 12, a first rotating shaft 13, a first rack 33 meshing with the first gear 12, and a connecting plate 32. The first rack 33 is vertically and slidably connected in the connecting block 40. Both ends of the connecting plate 32 are fixedly connected to one side of the first rack 33 and one side of the pressing rod 30 respectively. The first rotating shaft 13 is rotatably connected to the moving block 42. The cutting knife 11 is sleeved on the first rotating shaft 13. The first gear 12 is coaxially and fixedly connected to one end of the first rotating shaft 13. Specifically, when the pressing rod 30 moves downward towards the winding roller 7, at this time, the moving block 42 no longer undergoes horizontal displacement. The pressing rod 30 drives the first rack 33 to move downward synchronously through the connecting plate 32. The first rack 33 meshes with the first gear 12 for transmission, and drives the cutting knife 11 to rotate through the first rotating shaft 13 to cut a section of nylon plastic tube clamped by the clamping jaw 4. Since this section of waste tube has been deformed, cutting it can improve the overall quality of the nylon plastic tube, and the cut nylon plastic waste tube can be recycled for a second time, reducing the waste tube rate and improving the utilization rate of the product.

[0033] As a preferred technical solution, the second linkage assembly includes a first bevel gear 14, a second bevel gear 15 meshing with the first bevel gear 14, a second rotating shaft 16, a ratchet wheel 17 and a pawl 18 meshing with the ratchet wheel 17. The first bevel gear 14 is coaxially and fixedly connected to the other end of the first rotating shaft 13. The second rotating shaft 16 is rotatably connected in the moving block 42. Both ends of the second rotating shaft 16 are coaxially and fixedly connected to the ratchet wheel 17 and the second bevel gear 15 respectively. A limiting column 19 is fixedly connected to the processing table 1. The pawl 18 is in abutting cooperation with the limiting column 19. The pawl 18 is rotatably connected to the processing table 1. A resetting member is provided between the pawl 18 and the processing table 1. Specifically, after cutting the waste tube, the moving block 42 first moves towards the direction of the extruder 2 to the other side of the pressing rod 30 to prevent the thickness of the wound nylon plastic tube from increasing after winding, which hinders the movement path of the moving block 42. And when the pressing rod 30 resets, at this time, the winding is over, the moving block 42 moves towards the extruder 2, and when the ratchet wheel 17 meshes with the pawl 18, at this time, the limiting column 19 restricts the rotation of the pawl 18, causing the ratchet wheel 17 to rotate, driving the second bevel gear 15 to rotate through the second rotating shaft 16. The second bevel gear 15 meshes with the first bevel gear 14 for transmission, and the first bevel gear 14 drives the cutting knife 11 to rotate in the reverse direction through the first rotating shaft 13 to cut the nylon plastic tube at the outlet of the extruder 2, cutting off an unformed section of the nylon plastic tube at the extruder 2 end, improving the finished product quality and facilitating the subsequent bundling operation of the nylon plastic tube on the winding roller 7. At this time, the cutting knife 11 also resets to the initial state, facilitating the next operation.

[0034] As a preferred technical solution, the reset member includes a torsion spring 21. A cylinder 20 is vertically provided on the processing table 1. The pawl 18 is rotatably sleeved on the cylinder 20. The torsion spring 21 is arranged between the cylinder 20 and the pawl 18. Specifically, during the process that the ratchet 17 moves horizontally towards the roller 7 along with the moving block 42, due to the arrangement of the torsion spring 21, the ratchet 17 is not engaged with the pawl 18, avoiding the cutting knife 11 from cutting the nylon plastic pipe and affecting the clamping and dragging of the clamping jaw 4.

[0035] As a preferred technical solution, a connecting bracket 8 is provided on one side of the moving block 42. A guiding groove 10 is horizontally formed on the processing table 1. The connecting bracket 8 is slidably connected to the guiding groove 10. A second rack 22 is provided at the bottom of the connecting bracket 8. A first sliding groove 26 is vertically formed in the processing table 1. A screw rod 25 is rotatably connected in the first sliding groove 26. A slider 24 is vertically slidably connected in the first sliding groove 26. The bottom end of the screw rod 25 is coaxially and fixedly connected with a second gear 23. The second gear 23 is meshed with the second rack 22. The screw rod 25 is screwed with the slider 24. A connecting rod 27 is horizontally and fixedly connected to one side of the slider 24. A guiding roller 6 is rotatably sleeved on the connecting rod 27. Specifically, the moving block 42 and the connecting bracket 8 are displaced synchronously. And when the moving block 42 passes above the guiding roller 6, the second rack 22 and the second gear 23 are engaged and driven. The second gear 23 drives the screw rod 25 to rotate. At this time, the first sliding groove 26 restricts the circumferential rotation of the slider 24. The slider 24 vertically moves upward under the screw drive of the screw rod 25, which can avoid the direct contact between the nylon plastic pipe and the surface of the device, reduce friction, prevent surface damage, can control the tension of the nylon plastic pipe, and ensure the smooth extrusion process. Preferably, a first guiding rod 9 is horizontally arranged in the processing table 1. The connecting bracket 8 is slidably sleeved on the first guiding rod 9 to avoid the vertical displacement of the connecting bracket 8.

[0036] Working principle: The hydrolysis-resistant nylon-based composite material balanced extrusion system can be set to drive the connecting bracket 8 to move by a linear motor, control the moving speed of the clamping jaw 4 to adapt to the extrusion speed of the extruder 2, and avoid the breakage of the nylon plastic pipe caused by too fast dragging. When the extruder 2 extrudes the nylon plastic pipe, the clamping jaw 4 clamps it and drags the nylon plastic pipe to move towards the winding roller 7 along with the moving block 42. At this time, the ratchet wheel 17 does not engage with the pawl 18. After the moving block 42 passes above the guide roller 6, the second rack 22 engages with the second gear 23 for transmission, and the second gear 23 drives the screw 25 to rotate. The slider 24 moves vertically upward under the screw drive of the screw 25, which can prevent the nylon plastic pipe from directly contacting the surface of the equipment, reduce friction, and prevent surface damage. It can control the tension of the nylon plastic pipe to ensure a smooth extrusion process. When the pushing block 41 abuts against the abutting block 28, the pushing block 41 drives the abutting block 28 to move horizontally away from the extruder 2, and the inserting rod 29 disengages from the jack 31 on the pressing rod 30. The pressing rod 30 moves downward towards the winding roller 7 and fixes this section of the nylon plastic pipe on the winding roller 7 through clamping with the winding roller 7, improving personal safety, reducing risks such as pinching and the rebound of the nylon plastic pipe, facilitating subsequent winding and collection, and improving work efficiency. The pressing rod 30 drives the first rack 33 to move downward synchronously through the connecting plate 32. The first rack 33 engages with the first gear 12 for transmission, and drives the cutting knife 11 to rotate through the first rotating shaft 13 to cut a section of the nylon plastic pipe clamped by the clamping jaw 4. Since this section of the waste pipe has been deformed, cutting it can improve the overall quality of the nylon plastic pipe, can perform secondary treatment on the recycled plastic pipe, reduce the waste pipe rate, and improve the utilization rate of the product. After cutting the waste pipe, the moving block 42 first moves towards the extruder 2 to the other side of the pressing rod 30 to avoid the increase in the winding thickness of the nylon plastic pipe after winding, which hinders the movement path of the moving block 42. And when the pressing rod 30 resets, at this time the winding ends, and the moving block 42 moves towards the extruder 2. And when the ratchet wheel 17 engages with the pawl 18, at this time, the limiting column 19 restricts the rotation of the pawl 18, causing the ratchet wheel 17 to rotate, driving the second bevel gear 15 to rotate through the second rotating shaft 16. The second bevel gear 15 engages with the first bevel gear 14 for transmission, and the first bevel gear 14 drives the cutting knife 11 to rotate in the reverse direction through the first rotating shaft 13 to cut the nylon plastic pipe at the extrusion port of the extruder 2, facilitating the subsequent bundling operation of the nylon plastic pipe on the winding roller 7. At this time, the cutting knife 11 also resets to the initial state, facilitating the next operation.
