Description

Technical Field

[0001] This utility model relates to the field of material supply technology, and in particular to a central material supply system for polymer material production. Background Technology

[0002] Polymer materials, also known as polymer materials, can be used to manufacture plastic products. Specific polymer materials include polyethylene, polypropylene, and polyvinyl chloride. They soften when heated and harden when cooled, and can be repeatedly processed. In production workshops, a central feeding system is generally needed to distribute and supply polymer materials so that the raw materials can be stably delivered to the corresponding production equipment.

[0003] In the current operation of the central feeding system, after feeding one production device, the conveying pump is turned off, and then the feeding pipe is transferred to another production device for feeding. This feeding process causes the conveying pump to be repeatedly started and stopped, which will seriously shorten the service life of the conveying pump.

[0004] Therefore, how to provide a central feeding system for polymer material production is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a central feeding system for polymer material production. This invention solves the problem that existing central feeding systems require repeated starting and stopping of the feeding pump during the feeding process of different production equipment, which shortens the service life of the feeding pump.

[0006] According to an embodiment of the present invention, a central feeding system for polymer material production includes a central storage chamber. A central feed pipe is provided at the top of the central storage chamber, a conveying pump is provided at the bottom of the central storage chamber, a conveying pipe is provided at the output port of the conveying pump, a transfer component is provided on the conveying pipe, a feeding pipe is provided on the transfer component, and a temporary storage component is provided on the feeding pipe.

[0007] The temporary storage assembly includes a temporary storage tank for temporarily storing polymer materials.

[0008] The top of the temporary storage tank is equipped with a docking assembly, which includes a connecting pipe, a nut connector, and a docking ring. The connecting pipe is located on the top of the temporary storage tank, and the docking ring is fixed to the end of the feed pipe near the connecting pipe. The nut connector is sleeved on the feed pipe and the docking ring, and the nut connector is threaded onto the connecting pipe to position the connecting pipe and the docking ring.

[0009] The bottom of the temporary storage tank is provided with a telescopic tube assembly, which includes a fixed tube and a movable tube. The fixed tube is fixed to the bottom of the temporary storage tank, and the movable tube is movably sleeved on the surface of the fixed tube. The temporary storage assembly also includes an electrically controlled valve for controlling the discharge, which is located on the movable tube away from the fixed tube.

[0010] The movable tube is provided with a drive assembly for controlling the movement of the movable tube, and the drive assembly includes an adjustment assembly and a power assembly for driving the adjustment assembly.

[0011] The power assembly includes a drive motor, a drive gear, a transfer ring, a fixed ring, and a fixed plate. The fixed plate is fixed to the surface of the temporary storage tank near the bottom. The fixed ring is fixed to the lower surface of the fixed plate. The transfer ring is rotatably connected to the inner wall of the fixed ring via a bearing. Annular tooth grooves are provided on both the side and inner wall of the transfer ring. The drive gear meshes with the annular tooth grooves on the outer side of the transfer ring. The drive motor is fixed to the side of the fixed plate, and the drive gear is mounted on the output shaft of the drive motor.

[0012] The number of adjustment components is two sets, and the two sets of adjustment components are arranged symmetrically with respect to the vertical axis of symmetry of the movable tube.

[0013] The adjustment assembly includes a threaded seat, a threaded adjusting rod, and a transmission gear. The threaded seat is fixed to the surface of the movable tube near the top end. The top end of the threaded adjusting rod is rotatably connected to the lower surface of the fixed plate, and the threaded adjusting rod is located inside the intermediate ring and the fixed ring. The threaded seat is threaded onto the surface of the threaded adjusting rod. The transmission gear is fixedly sleeved on the surface of the threaded adjusting rod near the annular tooth groove. The transmission gear meshes with the annular tooth groove on the inner side of the intermediate ring.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a temporary storage component, during the feeding process of the central feeding system, after feeding one production device, it is only necessary to close the electrically controlled valve on the temporary storage component. In this way, the feed pump continues to feed material through the temporary storage component in the feeding pipeline network. Then, the feeding pipeline is adjusted to another production device through the transfer component, and the electrically controlled valve is opened again. At this time, the material stored in the temporary storage component is fed to the production device through the opened electrically controlled valve. There is no need to stop the feed pump during the entire feeding process, which solves the problem of the existing central feeding system requiring repeated start-stop of the feed pump during the feeding of different production devices, thus shortening the service life of the feed pump.

[0016] By setting up a telescopic tube assembly, the height of the discharge port can be adjusted by extending and contracting to match production equipment of different heights.

[0017] By setting up a drive component, the drive component automatically drives the telescopic tube assembly to extend and retract, thus achieving the purpose of automating the movement of the telescopic tube assembly. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Example 1:

[0025] refer to Figure 1The system includes a central storage chamber 1, with a central feed pipe 2 at the top and a feed pump 3 at the bottom. A feed pipe 4 is connected to the output port of the feed pump 3, and a transfer assembly 5 is installed on the feed pipe 4 for transferring materials and controlling the position of the feed pipe 6 (an existing assembly, not described in detail here). The transfer assembly 5 has a feed pipe 6, and a temporary storage assembly 7 is installed on the feed pipe 6. The temporary storage assembly 7 includes a temporary storage tank 8 for temporarily storing polymer materials and an electrically controlled valve 16 for controlling the discharge. During operation, [further details are needed]. When transferring the feed pipe 6 to the next production equipment, first close the solenoid valve 16. Then, the material output by the feed pump 3 passes through the feed pipe 4, the transfer assembly 5, and the feed pipe 6 to reach the temporary storage tank 8 for temporary storage. This eliminates the need to stop the feed pump 3. After the feed pipe 6 rotates to the position of the production equipment through the transfer assembly 5, open the solenoid valve 16 to discharge the material in the temporary storage tank 8. It should be noted that the maximum discharge speed controlled by the solenoid valve 16 is much greater than the conveying speed of the feed pump 3, which allows the material inside the temporary storage tank 8 to be quickly supplied to the production equipment.

[0026] Example 2:

[0027] refer to Figure 2 and Figure 3 The temporary storage tank 8 is equipped with a docking assembly 9 at its top. The docking assembly 9 includes a connecting pipe 10, a nut-and-connector 11, and a docking ring 12. The connecting pipe 10 is located at the top of the temporary storage tank 8. The docking ring 12 is fixed to the end of the feed pipe 6 near the connecting pipe 10. The nut-and-connector 11 is sleeved on the feed pipe 6 and the docking ring 12. The nut-and-connector 11 is threaded onto the connecting pipe 10, positioning the connecting pipe 10 and the docking ring 12. Fixing the docking ring 12 fixes the positions of the feed pipe 6 and the connecting pipe 10, thus allowing the material to pass through. Material can be stably supplied to the temporary storage tank 8 through the feeding pipe 6. It should be noted that the outer side of the connecting pipe 10 is provided with external threads, which match the threads on the nut connector 11. This allows the nut connector 11 to connect with the connecting pipe 10. When it is necessary to remove the temporary storage tank 8, first rotate the nut connector 11 to separate it from the connecting pipe 10. This makes it easy to remove the temporary storage tank 8. The installation method is the reverse of the above operation, which achieves the purpose of replacing the temporary storage tank 8.

[0028] Example 3:

[0029] refer to Figure 2 and Figure 3In this embodiment, a telescopic tube assembly 13 is provided at the bottom of the temporary storage tank 8. The telescopic tube assembly 13 includes a fixed tube 14 and a movable tube 15. The fixed tube 14 is fixed to the bottom of the temporary storage tank 8, and the movable tube 15 is movably sleeved on the surface of the fixed tube 14. An electrically controlled valve 16 is set on the movable tube 15 at a position away from the fixed tube 14. The electrically controlled valve 16 is installed on the movable tube 15 to facilitate the control of material discharge. During operation, when encountering different production equipment heights, it is necessary to move the movable tube 15 to move it up and down on the fixed tube 14. The height of the discharge port of the movable tube 15 is adjusted by moving the movable tube 15 to match the height of different production equipment, making the material supply more stable and faster.

[0030] Example 4:

[0031] refer to Figure 2 and Figure 3 The movable tube 15 is equipped with a drive assembly 17 for controlling its movement. This drive assembly 17 is provided to facilitate control of the movable tube 15. It primarily drives the movable tube 15 to move on the fixed tube 14. The drive assembly 17 includes an adjustment assembly 18 and a power assembly 19 for driving the adjustment assembly 18. There are two sets of adjustment assemblies 18, arranged symmetrically about the vertical axis of symmetry of the movable tube 15. This symmetrical arrangement ensures balanced force distribution during movement, preventing the movable tube 15 from getting stuck. The power assembly 19 includes a drive motor 20, a drive gear 21, a transfer ring 22, a fixed ring 23, and a fixed plate 24. The fixing plate 24 is fixed to the surface of the temporary storage tank 8 near the bottom. The fixing ring 23 is fixed to the lower surface of the fixing plate 24. The transfer ring 22 is rotatably connected to the inner wall of the fixing ring 23 through a bearing. The side and inner wall of the transfer ring 22 are provided with annular tooth grooves 25. The drive gear 21 meshes with the annular tooth grooves 25 on the outer side of the transfer ring 22. The drive motor 20 is fixed to the side of the fixing plate 24. The drive gear 21 is set on the output shaft of the drive motor 20. During operation, the drive motor 20 is started. The start of the drive motor 20 will drive the drive gear 21 to rotate. The rotation of the drive gear 21 will drive the transfer ring 22 to rotate on the fixing ring 23. The rotation of the transfer ring 22 will simultaneously drive the two sets of adjustment components 18 to move synchronously.

[0032] refer to Figure 3The adjusting assembly 18 includes a threaded seat 26, a threaded adjusting rod 27, and a transmission gear 28. The threaded seat 26 is fixed to the surface of the movable tube 15 near its top end. The top end of the threaded adjusting rod 27 is rotatably connected to the lower surface of the fixed plate 24, and the threaded adjusting rod 27 is located inside the transfer ring 22 and the fixed ring 23. The threaded seat 26 is threaded onto the surface of the threaded adjusting rod 27. It should be noted that when the transfer ring 22 rotates, it drives the two sets of transmission gears 28 to rotate. The two sets of transmission gears 28 rotate in the same direction. The transmission gears 28 are fixedly sleeved on the surface of the threaded adjusting rod 27 near the annular tooth groove 25. The transmission gears 28 and the transfer ring 24 are connected to the movable tube 15. The annular tooth groove 25 on the inner side of the ring 22 engages. During operation, the rotation of the transfer ring 22 drives the two sets of transmission gears 28 to rotate through the annular tooth groove 25 inside the transfer ring 22. The rotation of the two sets of transmission gears 28 drives the two sets of threaded adjusting rods 27 to rotate. The rotation of the two sets of threaded adjusting rods 27 drives the two sets of threaded seats 26 to move up and down on the two sets of threaded adjusting rods 27. The up and down movement of the two sets of threaded seats 26 will stably drive the movable tube 15 to move up and down on the fixed tube 14, thereby achieving the purpose of automatically controlling the movement of the movable tube 15. In this way, there is no need for manual movement, and the height of the discharge port on the movable tube 15 is automatically controlled during the feeding process to match the height of different production equipment.
