Description

Technical Field

[0001] The invention relates to the technical field of plastic product molding processing, in particular to a feeding machine for a rubber-plastic composite cable material production line. Background Art

[0002] The main raw materials of rubber composite cables include conductors, insulation layers, sheaths, etc., among which the cable sheath is made of composite rubber materials. In the production of composite rubber, it is necessary to mix rubber raw material particles, plasticizers, processing aids and other raw materials, and then extrude them into the required cross-sectional shape and size of the sheath through an extruder after processing. When mixing rubber, it is necessary to convey rubber raw material particles, plasticizers, processing aids and other raw materials through a feeder.

[0003] The existing feeder of the rubber-plastic composite cable material production line generally only uses the conveying screw to convey and extrude during use. This extrusion method relies on the friction between the raw material and the inner wall, as well as the thrust of the conveying screw for conveying. As the amount of raw materials decreases, the raw materials gradually fail to fill the entire pipeline, which leads to a weakening of the extrusion strength. The thrust of the feeding process is not uniform and stable enough, and it is difficult to mix and stir the raw materials synchronously during the conveying process. The raw materials need to be mixed in advance and then input into the pipeline, which increases the operation steps and reduces the production efficiency. To this end, we propose a feeder for the rubber-plastic composite cable material production line. Summary of the invention

[0030] The extrusion mechanism 11 includes a collecting barrel 12 fixedly mounted on the machine body 1. A stirring rod may be provided in the collecting barrel 12 for further stirring and mixing operations. One end of the conveying barrel 2 is connected to the top of the collecting barrel 12.

A push plate 14 is slidably connected in the extrusion barrel 13, which is used to collect and store the raw materials through the collecting barrel 12. The two groups of push plates 14 slide back and forth alternately, so that the raw materials in the collecting barrel 12 are continuously sucked into the extrusion barrel 13, and at the same time, the extrusion barrel 13 continuously squeezes the raw materials through the output pipe 3 for discharge.

[0031] The mixing element 10 includes a fixing frame 15 fixedly mounted on the machine body 1, a fixing rod 16 is fixedly connected to the fixing frame 15, one end of the fixing rod 16 is fixedly connected to the inner wall of the feed hopper 4, a rotating ring 17 rotatably connected to the outer wall of the fixing rod 16 is rotatably connected in the baffle 6, one end of the driving tube 7 is fixedly connected to the rotating ring 17, a rotating tube 18 is coaxially fixedly connected to the rotating ring 17, one end of the rotating tube 18 away from the rotating ring 17 is fixedly connected to a conical rod 44 rotatably connected to the outer wall of the fixing rod 16, a plurality of stirring elements 19 for pushing the raw materials for transportation and stirring are arranged between the rotating tube 18 and the driving tube 7, and a driving element 20 for driving the rotating ring 17 to rotate is arranged on the machine body 1.

[0032] The driving member 20 includes a driving motor 36 fixedly mounted on the fixed frame 15. The model of the driving motor 36 is preferably YYHS-40. The output end of the driving motor 36 is coaxially fixedly connected to the first gear 37. The side of the rotating ring 17 away from the driving tube 7 is coaxially fixedly connected to an outer gear ring 38 meshing with the first gear 37.

[0033] The stirring member 19 includes multiple groups of driving blades 21 fixedly installed on the outer wall of the rotating tube 18, one side of the driving blade 21 is fixedly connected to the inner wall of the driving tube 7, the rotating tube 18 is rotatably connected to multiple groups of stirring shafts 22 rotatably connected to the inner wall of the driving tube 7, the outer wall of the stirring shaft 22 is evenly fixedly connected to multiple groups of stirring rods 23, the outer wall of the fixed rod 16 is evenly fixedly connected to multiple groups of bevel gear rings 24, and one end of the stirring shaft 22 is coaxially fixedly connected to a bevel gear 25 meshing with the bevel gear ring 24.

[0034] In this embodiment, the raw materials are quantitatively put into the feed hopper 4 in the required proportion, and transported downward to the area between the driving tube 7 and the rotating tube 18 in the middle. The driving motor 36 is started to drive the first gear 37 to rotate, so that the outer gear ring 38 drives the rotating ring 17 to rotate, and the rotating ring 17 drives the driving tube 7 and the rotating tube 18 to rotate together. At this time, the inclined driving blades 21 will push the raw materials to one end of the output groove 9 for transportation. At the same time, the bevel gear 25 on the stirring shaft 22 will rotate around the bevel gear ring 24, thereby driving the stirring shaft 22 to rotate, and the stirring shaft 22 drives the stirring rod 23 to rotate and stir, so that the raw materials transported inside the driving tube 7 are mixed and distributed more evenly.

[0035] The raw materials in the driving tube 7 are output to the area between the outer side of the driving tube 7 and the conveying cylinder 2 through the output groove 9. At this time, the conveying screw 8 on the outer wall of the driving tube 7 will continuously push the raw materials to the position of the other end and fall into the collecting cylinder 12 for collection and storage. In this process, the thrust of the conveying screw 8 is more stable than that of the driving blade 21, which improves the strength of the conveying. At the same time, the raw materials are transported in the form of sleeve conveying, which reduces the volume of the equipment. At the same time, it can realize multiple functions such as conveying and stirring and mixing during the rotation of the driving tube 7, thereby improving the utilization efficiency of the equipment.

[0036] The extrusion mechanism 11 controls the two groups of push plates 14 to slide back and forth alternately, and the raw materials in the collecting cylinder 12 are continuously sucked into the extrusion cylinder 13. At the same time, the extrusion cylinder 13 continuously squeezes the raw materials out through the output pipe 3. The two groups of extrusion cylinders 13 alternately suck and squeeze and transport, which improves the stability of raw material transportation and makes the extrusion strength of the raw materials relatively uniform, reduces the interference of external factors, and is more convenient to use. Example

[0037] See also Figure 1-Figure 11 Embodiment 2 is described. This embodiment further describes Embodiment 1. The extrusion mechanism 11 shown in the figure also includes a connecting plate 26 fixedly mounted on the output pipe 3. One ends of the two groups of extrusion cylinders 13 are fixedly connected to the connecting plate 26. The bottom end of the collecting cylinder 12 is provided with two groups of first connecting holes 27 respectively connected to the extrusion cylinders 13 on both sides. The connecting plate 26 is provided with two groups of second connecting holes 28 respectively connected to the output pipe 3 and the two groups of extrusion cylinders 13. The first connecting hole 27 and the second connecting hole 28 are both provided with a conveying member 29 for controlling the unidirectional conveying of the raw material. The machine body 1 is provided with an extrusion member 30 for driving the push plates 14 on both sides to perform alternating reciprocating movements when the driving member 20 is running.

[0038] The conveying member 29 includes a fixed ring 31 fixedly installed in the first connecting hole 27 and the second connecting hole 28, a return spring 32 is fixedly connected to the fixed ring 31, a control block 33 is slidably connected in the fixed ring 31, one end of the return spring 32 is fixedly connected to the control block 33, a feed pipe 34 is provided on the control block 33, and a side hole 35 connected to the feed pipe 34 is provided on the side of the control block 33.

[0039] The extrusion piece 30 includes a reciprocating screw 39 rotatably connected to the body 1, one end of the reciprocating screw 39 is coaxially fixedly connected to a second gear 40 meshing with the first gear 37, one side of the two sets of push plates 14 are respectively fixedly connected to a rack 41, a third gear 42 meshing with the racks 41 on both sides is rotatably connected to the body 1, one end of a set of racks 41 is fixedly connected to a drive rod 43, the reciprocating screw 39 passes through the drive rod 43, and is threadedly connected to the drive rod 43.

[0040] In this embodiment, the first gear 37 drives the second gear 40 during the rotation process to rotate the reciprocating screw 39, and the reciprocating screw 39 drives the driving rod 43 to slide back and forth, thereby driving the rack 41 on one side to reciprocate with the push plate 14, and the rack 41 drives the third gear 42 to make the rack 41 on the other side move in the opposite direction, so that when the push plate 14 on one side moves toward the connecting plate 26, the push plate 14 on the other side moves away from the connecting plate 26. At this time, the push plate 14 away from the connecting plate 26 4 will pump the raw material in the collecting cylinder 12 downward, push the control block 33 in the first communicating hole 27 to move downward, so that the side hole 35 on the control block 33 is connected with the extrusion cylinder 13 below, so that the raw material is output to the extrusion cylinder 13 through the feeding pipe 34 and the side hole 35. In this process, the control block 33 at one end of the extrusion cylinder 13 close to the second communicating hole 28 is pulled toward the pushing plate 14, so that the side hole 35 on the control block 33 is sealed with the inner wall of the fixing ring 31, thereby preventing the raw material in the output pipe 3 from flowing back.

[0041] At this time, the pushing plate 14 moving toward the connecting plate 26 on the other side will squeeze the raw material in the extrusion barrel 13 and push it toward the second connecting hole 28. The raw material pushes the control block 33 to compress the reset spring 32, so that the side hole 35 is gradually connected with the output pipe 3, and the raw material is output to the output pipe 3 through the feed pipe 34 and the side hole 35, and is extruded through the extrusion head 45. During this process, the extruded raw material in the extrusion barrel 13 will push the control block 33 in the first connecting hole 27 to move upward, so that the side hole 35 on the control block 33 moves upward and contacts and seals with the inner wall of the fixing ring 31, so as to prevent the raw material in the extrusion barrel 13 from flowing back into the collecting barrel 12. In this way, the purpose of extrusion on one side and suction on the other side can be achieved by reciprocating, thereby realizing continuous and stable extrusion and conveying operation, and the output intensity will not be reduced due to the reduction in the amount of raw materials, and the conveying intensity is relatively stable.
