Description

[0002] As we all know, plastic extruder is an important equipment in the cable processing process. Extruding plastic during the cable processing process to ensure that the cable is plasticized on the outside is one of the key processes in cable processing.

[0003] Existing plastic extruders usually use screw conveyors for feeding. The screw conveyor has a simple structure and is easy to operate, but there are still problems in use. In the process of the screw conveyor conveying materials and injecting the materials into the extruder, faults will occur due to uneven materials, which not only affects the uniform and stable injection of materials into the extruder, but also makes it difficult to ensure the feeding amount. What is more serious is that after the feeding is completed, a large amount of materials often remain inside the screw conveyor. These materials are easy to solidify inside the conveyor after cooling, which is not only difficult to clean, but also seriously affects the subsequent use of the screw conveyor.

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0028] A feeding device for a cable extruder according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0029] like Figure 1-Figure 4 As shown, a feeding device for a cable extruder according to an embodiment of the utility model may include a box body 1, a screw conveyor 2, a synchronous drive component 3, a downward pressure tube component 4, a vibrator 5, a control component 6, a shock absorbing frame 7 and an electric heating device 8.

[0030] It should be noted that a feed pipe and a discharge pipe are respectively provided on the surface and the bottom of the box body 1 , material valves are respectively provided on the feed pipe and the discharge pipe, and a maintenance door is provided on the top of the box body 1 .

[0031] The electric heating device 8 is arranged on the inner wall of the box body 1 .

[0032] It should be noted that the electric heating device 8 is used to preheat the material inside the box 1 .

[0033] It should also be noted that the electric heating device 8 is a constant temperature heating device, and the electric heating device 8 is a heating plate. The principle of the heating plate is the existing technology, so it will not be repeated again.

[0034] The downward-pressing tube assembly 4 , the vibrator 5 and the control assembly 6 are respectively arranged on the surface of the box body 1 .

[0035] It should be noted that the vibrator 5 transmits vibration energy to the material inside the box 1 by generating mechanical vibration. This vibration helps to rearrange and tightly stack the material particles, thereby eliminating gaps in the material and improving the overall density and stability. After the material is processed by the vibrator 5, its overall structure becomes more compact and stable, which helps to maintain the uniformity of the material amount during the subsequent lifting process. In addition, the vibrator 5 also helps to reduce the adhesion of the material inside the box 1. In some cases, the material may adhere to the wall of the box 1 due to humidity, static electricity or other factors, which will not only affect the accuracy of the material amount, but also may cause damage to the box 1. The vibration generated by the vibrator 5 can effectively shake off the adhered material to keep the box 1 clean and the material fluidity. Of course, when using the vibrator 5, it is also necessary to pay attention to controlling the intensity and frequency of the vibration to avoid unnecessary damage to the material or equipment.

[0036] It should also be noted that the vibrator 5 is a prior art, so it will not be described in detail here.

[0037] The screw conveyor 2 and the shock absorbing frame 7 are respectively arranged at the top and the bottom of the box body 1 . One end of the screw conveyor 2 penetrates into the box body 1 and is located on one side of the electric heating device 8 .

[0038] It should be noted that the vibrator 5 corresponds to the position of one end of the screw conveyor 2 that penetrates into the interior of the box body 1. This design facilitates the vibration of the material at the feed port of the screw conveyor 2 and has a good use effect.

[0039] It should also be noted that the screw conveyor 2 is used to transport the material inside the box 1 to the inside of the downward pressure tube assembly 4. One end of the discharge pipe 21 of the screw conveyor 2 is connected to the inside of the downward pressure tube assembly 4. The screw conveyor 2 is a prior art and will not be described in detail here.

[0040] The synchronous driving assembly 3 may include a support frame 31 , a dual-axis motor 32 and a synchronous mechanism 33 .

[0041] Among them, the support frame 31 is bolted to the top of the box body 1 and is located on one side of the screw conveyor 2. The dual-axis motor 32 is bolted to the surface of the support frame 31. One end of the dual-axis motor 32 is connected to one end of the central axis of the screw conveyor 2 through a coupling 321. The synchronization mechanism 33 is arranged on the surface of the support frame 31. One end of the synchronization mechanism 33 is connected to one end of the dual-axis motor 32, and the other end of the synchronization mechanism 33 is connected to one end of the downward pressure tube assembly 4.

[0042] It should be noted that the support frame 31 serves as a supporting carrier for the dual-axis motor 32 and the synchronization mechanism 33, the dual-axis motor 32 serves as a power source, and the synchronization mechanism 33 serves as a transmission mechanism, so that while the dual-axis motor 32 drives the screw conveyor 2 to operate, the synchronization mechanism 33 synchronously drives the downward pressure tube assembly 4 to operate.

[0043] The control assembly 6 is connected to the synchronous drive assembly 3, the down-pressing tube assembly 4, the vibrator 5 and the electric heating device 8 respectively.

[0044] It should be noted that the control component 6 described in this embodiment has a built-in timing unit (not shown in the figure) and a wireless communication module (not shown in the figure). The timing unit is used for timing operation, and the wireless communication module is used to receive instructions sent from an external host computer to achieve remote control.

[0045] It should also be noted that a limit rod and a limit groove (not shown in the figure) are respectively provided at the positions corresponding to the bottom of the box body 1 and the top of the shock-absorbing frame 7. The limit rod is located inside the limit groove and is fixedly connected to the top of the shock-absorbing frame 7 through a nut. The limit rod, the limit groove and the nut are used to fix the box body 1. A rubber shock-absorbing pad (not shown in the figure) is provided at the connection between the bottom of the box body 1 and the top of the shock-absorbing frame 7. The rubber shock-absorbing pad effectively reduces the vibration from the box body 1 and has a good use effect.

[0046] Specifically, when in use, the control component 6 controls the electric heating device 8 and the vibrator 5 to be powered on and operated respectively. The electric heating device 8 is used to preheat the material inside the box 1. The vibrator 5 generates mechanical vibrations and transmits the vibration energy to the material inside the box 1, thereby eliminating gaps in the material, improving the overall density and stability, and helping to maintain the uniformity of the material amount during the subsequent lifting process. In addition, the vibrator 5 also helps to reduce the adhesion of the material inside the box 1.

[0047] After the vibrator 5 finishes running, the control component 6 controls the dual-axis motor 32 to be powered on and run, and the dual-axis motor 32 drives the screw conveyor 2 to run, and the screw conveyor 2 runs to transport the material inside the box 1 to the inside of the downward pressure tube assembly 4. At the same time, the operation of the dual-axis motor 32 also synchronously drives the synchronization mechanism 33 to run, and the operation of the synchronization mechanism 33 synchronously drives the downward pressure tube assembly 4 to run, and the operation of the downward pressure tube assembly 4 drives the piston 43 to rise.

[0048] When the screw conveyor 2 is running to quantitatively convey the material inside the box body 1 to the inside of the downward pressure tube assembly 4 (the conveying rate of the screw conveyor 2 can be controlled to control the feeding amount), the control component 6 controls the double-axis motor 32 to reverse, and the double-axis motor 32 reverses and synchronously drives the screw conveyor 2 to reverse. The screw conveyor 2 reverses and discharges the material inside it to the inside of the box body 1 again, and the material is heated by the electric heating device 8 to prevent the material from being fixed inside the screw conveyor 2, thereby affecting the use of the screw conveyor 2. The reversal of the double-axis motor 32 also synchronously drives the synchronization mechanism 33 to run, and the operation of the synchronization mechanism 33 synchronously drives the piston 43 in the downward pressure tube assembly 4 to descend. During the descent of the piston 43, the control component 6 controls the electromagnetic ball valve 44 to close, and drives the material inside the material barrel 41 to be evenly and stably injected into the feed pipe of the extruder through pressure. When the piston 43 rises next time, the control component 6 controls the electromagnetic ball valve 44 to open and adjust the air pressure to facilitate the rise of the piston 43.

[0049] The vibrator 5 is used to effectively eliminate material gaps, significantly improve material density and stability, ensure uniform material quantity during subsequent lifting, and prevent faults. The synchronous drive component 3 accurately controls the operation of the screw conveyor 2 and the down-pressure tube component 4 to ensure that the set amount of material is accurately transported to the inside of the down-pressure tube component 4, and then injected into the extruder evenly and stably by the down-pressure tube component 4, which greatly enhances production stability. What is more worth mentioning is that the synchronous drive component 3 can also drive the screw conveyor 2 to run in reverse, easily discharge the internal material back to the box 1, and completely avoid the problem of material solidification inside the screw conveyor 2, thereby optimizing the overall operation process.

[0050] In one embodiment of the present invention, Figure 3 As shown, an encoder 322 is bolted on the surface of the dual-axis motor 32 , and the dual-axis motor 32 and the encoder 322 are electrically connected to the control component 6 respectively.

[0051] It should be noted that the encoder 322 described in this embodiment is used to detect the number of rotations of the dual-axis motor 32 in real time, and send the relevant number of rotations data to the controller 62 in the control component 6. The controller 62 determines the feeding amount of the screw conveyor 2 and the position of the piston 43 based on the number of rotations data.

[0052] In one embodiment of the present invention, Figure 3 As shown, the synchronization mechanism 33 may include a rotating shaft 331 , a reciprocating screw 332 , a synchronization gear 333 , a synchronization belt 334 , a guide limit rod 335 and a lifting slide 336 .

[0053] Among them, the rotating shaft 331 is rotatably connected to the surface of the support frame 31 and is fixedly connected to one end of the dual-axis motor 32. The reciprocating screw rod 332 is rotatably connected to the surface of the support frame 31 and is located on one side of the rotating shaft 331. The guide limit rod 335 is fixedly connected to the surface of the support frame 31 and is located on one side of the reciprocating screw rod 332. Synchronous gears 333 are respectively provided at corresponding positions on the surface of the reciprocating screw rod 332 and the surface of the guide limit rod 335, and are connected through a synchronous toothed belt 334. The lifting slide 336 is threadedly connected to the outer surface of the reciprocating screw rod 332 and is slidably connected to the outer surface of the guide limit rod 335. The bottom of one end of the lifting slide 336 is connected to one end of the downward pressure tube assembly 4.

[0054] It should be noted that the lifting slide 336 described in this embodiment reciprocates up and down along the surface of the reciprocating screw 332. The movement principle and related structure of the lifting slide 336 on the surface of the reciprocating screw 332 are existing technologies and will not be described in detail here.

[0055] Specifically, the dual-axis motor 32 synchronously drives the rotating shaft 331 to rotate, and the rotation of the rotating shaft 331 synchronously drives the reciprocating screw 332 to rotate through the cooperation of the synchronous gear 333 and the synchronous toothed belt 334. The rotation of the reciprocating screw 332 synchronously drives the lifting slide 336 to reciprocate up and down along the outer surface of the reciprocating screw 332 and the outer surface of the guide limit rod 335. The lifting slide 336 synchronously drives the downward pressure tube assembly 4 to operate during the lifting process.

[0056] In one embodiment of the present invention, Figure 4 As shown, the pressing tube assembly 4 may include a material lowering barrel 41 , a lifting rod 42 , a piston 43 and two sets of electromagnetic ball valves 44 .

[0057] Among them, the discharge barrel 41 is fixedly connected to the surface of the box body 1, and the bottom of the discharge barrel 41 is fixedly connected to one end of the extruder feed pipe through a flange and fixing bolts, and is connected. The lifting rod 42 is slidably connected to the top of the discharge barrel 41, and one end of the lifting rod 42 is fixedly connected to the bottom of one end of the lifting slide 336. The other end of the lifting rod 42 penetrates into the discharge barrel 41 and is fixedly connected with a piston 43. The piston 43 is slidably connected to the inner wall of the discharge barrel 41 and is adapted to the internal shape of the discharge barrel 41. The surface of the piston 43 is symmetrically provided with air grooves, and two groups of electromagnetic ball valves 44 are respectively arranged in the two groups of air grooves, and the two groups of electromagnetic ball valves 44 are respectively electrically connected to the control component 6.

[0058] It should be noted that the spherical valve body in the electromagnetic ball valve 44 described in this embodiment is rotatably connected to the inner wall of the air groove and is adapted to the internal dimensions of the air groove. An air hole is opened on the surface of the spherical valve body. When the air hole is in a vertical state, the top of the piston 43 and the bottom of the piston 43 are in a connected state. When the air hole is in a horizontal state, the inner wall of the air groove blocks the air hole, and the top of the piston 43 and the bottom of the piston 43 are not connected. The electromagnetic control end in the electromagnetic ball valve 44 is arranged inside the piston 43, and the circuit enters the piston 43 from the inside of the lifting rod 42, wherein the size of the air hole should meet the use of the piston 43 to rise.

[0059] It can be understood that when the material is transported to the interior of the discharge barrel 41 through the screw conveyor 2, the piston 43 has moved to the connection between the discharge pipe 21 and the interior of the down-pressure tube assembly 4. When the piston 43 moves to the top end of the down-pressure tube assembly 4, the material discharged into the down-pressure tube assembly 4 during this period is the single injection amount.

[0060] It is also understandable that in order to ensure that the piston 43 is located above the connection between the discharge pipe 21 and the lower pressure tube assembly 4 when the material enters the lower material barrel 41, its position needs to be debugged to ensure normal operation.

[0061] Specifically, the lifting slide 336 descends and the piston 43 descends synchronously. During the descending process of the piston 43, the controller 62 in the control component 6 controls the electromagnetic ball valve 44 to close, so that the upper part of the piston 43 and the lower part of the piston 43 are in a disconnected state, thereby facilitating the uniform injection of the material inside the discharge barrel 41 into the feed pipe of the extruder under the action of pressure. When the piston 43 rises, the controller 62 in the control component 6 controls the electromagnetic ball valve 44 to open, so that the upper part of the piston 43 and the lower part of the piston 43 are in a connected state, which is convenient for adjusting the air pressure, thereby facilitating the piston 43 to rise.

[0062] In one embodiment of the present invention, Figure 1 As shown, the control component 6 may include an electrical control box 61, a battery arranged inside the electrical control box 61, and a controller 62 arranged on the box door, the battery is electrically connected to the controller 62, and the controller 62 is electrically connected to the dual-axis motor 32, the encoder 322, the electromagnetic ball valve 44, the vibrator 5 and the electric heating device 8 respectively.

[0063] Specifically, the electrical equipment is controlled by the controller 62 respectively. The controller 62 has accurate control data, stable performance and good use effect.

[0064] In summary, a feeding device for a cable extruder according to an embodiment of the utility model effectively eliminates material gaps through a vibrator 5, significantly improves material density and stability, ensures a uniform material amount during subsequent lifting, and eliminates fault phenomena. The synchronous drive component 3 accurately controls the operation of the screw conveyor 2 and the down-pressure tube component 4, ensuring that a set amount of material is accurately transported to the inside of the down-pressure tube component 4, and then is uniformly and stably injected into the extruder by the down-pressure tube component 4, greatly enhancing production stability. It is worth mentioning that the synchronous drive component 3 can also drive the screw conveyor 2 to run in reverse, easily discharge the internal material back to the box 1, and completely avoid the problem of material solidification inside the screw conveyor 2, thereby optimizing the overall operation process.
