Description

Technical Field

[0001] The invention relates to the technical field of extruders, in particular to a feeding device of an extruder for processing an aluminum shell of a power capacitor. Background Art

[0002] An extruder is a device used to force various materials through a specific die to produce continuous profiles, pipes, rods and other products. It mainly relies on the rotation or linear motion of the screw to apply pressure to the material placed in the barrel, causing the material to undergo plastic deformation under the pressure, thereby extruding through the die hole of the die to form the desired shape. In plastic processing, plastic particles are added to the barrel of the extruder, and the rotation of the screw pushes the plastic particles forward. At the same time, the plastic gradually melts under the action of heating and the shear force of the screw. Then, the molten plastic passes through the die under the push of the screw and is extruded into various plastic products, such as plastic pipes, plastic profiles, etc. The aluminum shell of the power capacitor needs to be transported and fed before entering the bottom of the extruder. Therefore, a feeding device for an extruder for processing the aluminum shell of a power capacitor is particularly needed.

[0003] However, the traditional feeding method uses manual handling to feed materials, which is inefficient. Workers' physical strength and speed are limited, and it cannot meet the needs of large-scale production for rapid material supply, which easily leads to long waiting times in the production process, thereby reducing the production efficiency of the entire production system. Some conveyor belts are used for feeding. After long-term use, the conveyor belts will become loose. The friction between the loose conveyor belt and the driving wheel and the driven wheel is unevenly distributed, and slippage may occur, so that the material cannot be transported at the predetermined speed, resulting in a sharp drop in production efficiency. Summary of the invention

Since the crawler track is tightly fitted with the first roller and the second roller, the rotation of the first roller drives the crawler track to move, and then the second roller rotates with the movement of the crawler track, and the transmission shaft at the inner end of the second roller also rotates accordingly. The rotation of the rotating shaft and the transmission shaft provides power for the conveyor belt, so that the conveyor belt starts to run.

The baffle can slide in the slot to accurately limit the position of the material on the conveyor belt and prevent the material from slipping from both sides of the conveyor belt during transportation, further ensuring the accuracy and stability of feeding, improving production efficiency, and ensuring that the material can be supplied to the extruder quickly, accurately, continuously and stably to meet the needs of large-scale production.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6The present invention provides a technical solution: a feeding device of an extruder for processing aluminum shells of power capacitors, comprising a bracket 1, a bottom pad 2 is fixedly connected to the bottom surface of the bracket 1, a support plate 3 is fixedly connected to the upper side of one end of the bracket 1, a material bin 4 is fixedly connected to the upper surface of the support plate 3, a push plate 5 is slidably connected to the inside of the support plate 3, a hydraulic rod 6 is fixedly connected to the outer end of the push plate 5, a hydraulic cylinder 7 is slidably connected to the outside of the hydraulic rod 6, a conveying device 8 is arranged on the surface of the bracket 1, and a positioning device 9 is arranged at one end of the bracket 1;

[0024] The conveying device 8 includes a fixed plate 801, a first motor 802, a first roller 803, a rotating shaft 804, a crawler 805, a second roller 806, a transmission shaft 807, a conveyor belt 808, a clamping shaft 809, a fixed shaft 810, a fixing ring 811, a threaded hole 812, a bolt 813, a plug hole 814, an insertion rod 815, a fixing rod 816, a slot 817 and a baffle 818. The surface of the bracket 1 is fixedly connected with the fixed plate 801, the upper surface of the fixed plate 801 is fixedly connected with the first motor 802, the inner end of the first motor 802 is fixedly connected with the first roller 803, the inner end of the first roller 803 is fixedly connected with the rotating shaft 804, the outer wall surface of the first roller 803 is attached with the crawler 805, and the other end of the crawler 805 is fixedly connected with the first roller 803. A second roller 806 is fitted on the inner wall surface of the end, and a transmission shaft 807 is fixedly connected to the inner end of the second roller 806. A conveyor belt 808 is fitted on the outer wall surface of one end of the rotating shaft 804 and the transmission shaft 807. A clamping shaft 809 is tightly pressed on the middle part of the inner wall of the conveyor belt 808. A fixed shaft 810 runs through the inside of the clamping shaft 809. A fixing ring 811 is sleeved on the outer end of the fixing shaft 810. Threaded holes 812 are provided on the surfaces of the bracket 1 and the fixing ring 811. Bolts 813 are threadedly connected to the inner wall surface of the threaded hole 812. A plug hole 814 is provided on the upper surface of the bracket 1. A plug rod 815 fits inside the plug hole 814. A fixing rod 816 is fixedly connected to the upper surface of the plug rod 815. A card slot 88 is provided on the inner side of the fixing rod 816. 17, the inner part of the card slot 817 is slidably connected with a baffle 818. Through the setting of the conveying device 8, when the device is started, the first motor 802 starts to run, driving the first roller 803 connected thereto to rotate, and the first roller 803 transmits power through the rotating shaft 804. Since the crawler belt 805 is closely fitted with the first roller 803 and the second roller 806, the rotation of the first roller 803 drives the crawler belt 805 to move, and then the second roller 806 rotates with the movement of the crawler belt 805, and the transmission shaft 807 at the inner end of the second roller 806 also rotates accordingly. The rotation of the rotating shaft 804 and the transmission shaft 807 provides power for the conveyor belt 808, so that the conveyor belt 808 starts to run. During the operation of the conveyor belt 808, the middle pressing The shaft 809, in cooperation with the fixed shaft 810 and the fixed ring 811, has a tensioning effect on the conveyor belt 808. The threaded connection between the bolt 813 and the threaded hole 812 can ensure the stability of the position of the fixed ring 811, thereby ensuring that the clamping shaft 809 can continuously and effectively apply appropriate pressure to the conveyor belt 808 to prevent the conveyor belt 808 from loosening. Even if the conveyor belt 808 has a slight loosening tendency during long-term use, this tensioning structure can be adjusted in time to prevent uneven friction and slipping caused by loose conveyor belts. At the same time, the cooperation between the socket 814 and the plug 815 and the design of the fixed rod 816, the slot 817, and the baffle 818 make it possible to flexibly adjust the boundaries of the conveying area according to the type and size of the material.The baffle 818 can slide in the slot 817 to accurately limit the position of the material on the conveyor belt and prevent the material from sliding off the two sides of the conveyor belt 808 during the conveying process, further ensuring the accuracy and stability of the feeding, improving the production efficiency, and ensuring that the material can be quickly, accurately, continuously and stably supplied to the extruder to meet the needs of large-scale production.

[0025] Furthermore, multiple groups of bottom pads 2 are arranged at the bottom of the bracket 1, and are symmetrically distributed at the four feet of the bottom of the bracket 1 with the central axis of the bracket 1. The arrangement of the bottom pads 2 enhances the stability of the entire feeding device. During the feeding process, especially when the conveyor belt 808 may vibrate and the center of gravity changes due to the movement of materials on the conveyor belt, the stable bracket structure can effectively prevent the device from shaking or tilting, thereby ensuring the accuracy and continuity of the feeding and reducing problems such as material falling and conveyor belt deviation caused by unstable device.

[0026] Furthermore, the first roller 803 and the first motor 802 cooperate with each other to form a rotating structure, and the track 805 drives the second roller 806 to rotate through the first roller 803. Through the arrangement of the first motor 802, the first roller 803, the track 805 and the second roller 806, the power generated by the first motor 802 can be efficiently and stably transmitted to the second roller 806 through the first roller 803 and the track 805, thereby driving the conveyor belt 808. Compared with some complex or fault-prone transmission methods, this structure is simple and stable, which reduces the energy loss and fault risk during power transmission, and is conducive to maintaining a stable feeding speed and ensuring production efficiency.

[0027] Furthermore, the fixing ring 811 is fixedly connected to the bracket 1 through the threaded hole 812 and the bolt 813. Two groups of bolts 813 are symmetrically arranged with respect to the central axis of the fixing ring 811. Through the arrangement of the fixing ring 811, the threaded hole 812 and the bolt 813, the connection between the fixing ring 811 and the bracket 1 is made more secure, thereby ensuring the reliability of the tensioning effect of the clamping shaft 809 on the conveyor belt 808. In the case that the tension of the conveyor belt 808 changes due to long-term operation, the stable tensioning structure can better adapt to such changes and prevent the conveyor belt 808 from loosening, thereby avoiding problems such as slipping and uneven material conveying speed caused by loose conveyor belts, thereby extending the service life of the conveyor belt 808 and reducing maintenance costs.

[0028] Furthermore, the outer wall size of the insertion rod 815 is consistent with the inner wall size of the hole 814, and the outer wall size of the baffle 818 is consistent with the inner wall size of the slot 817. Through the setting of the hole 814, the insertion rod 815, the slot 817 and the baffle 818, the operator can easily adjust the position of the baffle 818 according to the size and shape of different materials, ensuring that the material is accurately confined to the conveyor belt 808 during the conveying process, avoiding material overflow, improving the accuracy and efficiency of feeding, and also helping to keep the work area clean and tidy, reducing material waste and cleaning costs.

[0029] Furthermore, the positioning device 9 includes a positioning platform 901, a fixed block 902, a second motor 903, a first threaded rod 904, a stopper 905, a second threaded rod 906, a moving block 907, a limiting plate 908, a limiting block 909, a limiting groove 910 and a photoelectric sensor 911, one end of the bracket 1 is fixedly connected to the positioning platform 901, one end of the positioning platform 901 is fixedly connected to the fixed block 902, one side of the fixed block 902 is fixedly connected to the second motor 903, the inner end of the second motor 903 is fixedly connected to the first threaded rod 904, one end of the first threaded rod 904 is fixedly connected to the stopper 905, and the other end of the stopper 905 is fixedly connected to the second threaded rod 9 06, the surfaces of the first threaded rod 904 and the second threaded rod 906 are both threadedly connected with a moving block 907, the upper surface of the moving block 907 is fixedly connected with a limiting plate 908, the bottom of the limiting plate 908 is fixedly connected with a limiting block 909, the surface of the positioning platform 901 is provided with a limiting groove 910, and the upper surface of the limiting plate 908 is installed with a photoelectric sensor 911. Through the setting of the positioning device 9, when it is necessary to position the material, the second motor 903 is started, and the second motor 903 rotates to drive the first threaded rod 904 to rotate. Since the first threaded rod 904 is connected to the stopper 905, and the stopper 905 is connected to the second threaded rod 906, the first threaded rod 90 4 and the second threaded rod 906 rotate simultaneously, and the threads on the surfaces of the first threaded rod 904 and the second threaded rod 906 are in opposite directions. When they rotate, the moving blocks 907 threadedly connected thereto will move toward or away from each other. Because the two moving blocks 907 are respectively located on different threaded rods, such a design can ensure that the moving blocks 907 can achieve synchronous and stable displacement when the threaded rods rotate. The limiting plate 908 fixed above the moving block 907 moves with the moving block 907, and the limiting block 909 at the bottom of the limiting plate 908 slides in the limiting groove 910 on the surface of the positioning platform 901. The cooperation between the limiting groove 910 and the limiting block 909 provides a position for the movement of the limiting plate 908. Precise guidance prevents the limit plate 908 from deviating during movement and ensures the accuracy of its movement direction. When the material is conveyed to the positioning table 901, the photoelectric sensor 911 located above the limit plate 908 detects the material. The photoelectric sensor 911 senses whether the material is in place by detecting the material's obstruction of light. Once the photoelectric sensor 911 detects the material, the second motor 903 can stop rotating according to a preset program. At this time, the limit plate 908 and the moving block 907 stop moving, thereby accurately positioning the material at a predetermined position. This can ensure that the material has an accurate initial position in the subsequent processing process, thereby improving processing accuracy and product quality.

[0030] Furthermore, the first threaded rod 904 cooperates with the second motor 903, the block 905 and the second threaded rod 906 to form a rotating structure. The first threaded rod 904 and the second threaded rod 906 are symmetrically distributed with the central axis of the block 905. Through the arrangement of the first threaded rod 904, the block 905 and the second threaded rod 906, the first threaded rod 904 cooperates with the second motor 903, the block 905 and the second threaded rod 906 to form a rotating structure. This design ensures that the power transmission from the motor to the threaded rod is accurate and stable. The second motor 903, as a power source, can provide continuous and reliable power for the positioning process, so that the first threaded rod 904 and the second threaded rod 906 can accurately rotate according to instructions, thereby realizing the positioning of the object. In order to accurately control the positioning of materials and reduce the positioning error caused by unstable power transmission, it is of great significance that the first threaded rod 904 and the second threaded rod 906 are symmetrically distributed with the central axis of the stop block 905. This symmetrical structure enables the two threaded rods to maintain synchronous movement during rotation. When the second motor 903 is driven, the moving blocks 907 on the two threaded rods will move toward or away from each other at the same time. This synchronization is crucial for the accurate positioning of materials and can avoid problems such as uneven force on the materials and position offset caused by asynchronous movement of the two sides. At the same time, the symmetrical distribution also ensures the balance of the entire positioning device during operation, reduces the vibration and device wear that may be caused by unbalanced force, and improves the service life and reliability of the positioning device.

[0031] Furthermore, the position of the limit block 909 corresponds to the position of the limit slot 910, and the outer wall size of the limit block 909 is consistent with the inner wall size of the limit slot 910. Through the setting of the limit block 909 and the limit slot 910, during the operation of the positioning device, when the moving block 907 moves with the rotation of the first threaded rod 904 and the second threaded rod 906, the limit block 909 under the limit plate 908 slides in the limit slot 910. This precise fit ensures that the limit plate 908 can only move along the direction specified by the limit slot 910, thereby ensuring the accuracy of material positioning, avoiding deviations in material positioning due to the offset of the limit plate 908, and further ensuring the accuracy of subsequent processing links.

[0032] Working principle: First, the material in the silo 4 is ready to be transported. The push plate 5 under the silo 4 pushes the material toward the conveying device 8 under the push of the hydraulic rod 6. Then, in the conveying device 8, the first motor 802 is started to drive the first roller 803 to rotate. The rotating power is transmitted through the rotating shaft 804. With the help of the close fit between the crawler 805 and the first roller 803 and the second roller 806, the second roller 806 rotates with the movement of the crawler 805. The transmission shaft 807 at the inner end of the second roller 806 also starts to rotate. The rotating shaft 804 and the transmission shaft 807 jointly drive the conveyor belt 808 to run. At the same time, the tensioning device 811, the threaded hole 812 and the bolt 813 are used to tighten the conveyor belt 808. The structure ensures that the pressing shaft 809 effectively tightens the conveyor belt 808, and the cooperation of the plug rod 815, the plug hole 814, the slot 817 and the baffle 818 can adjust the conveying area boundary according to the actual situation of the material, ensuring that the material is stably conveyed on the conveyor belt 808 and will not slip from both sides. The material moves toward the positioning device 9 under the transportation of the conveyor belt 808. When the material reaches the positioning platform 901 of the positioning device 9, the second motor 903 on the side of the fixed block 902 is started to drive the first threaded rod 904 to rotate. The first threaded rod 904 drives the second threaded rod 906 to rotate at the same time through the stop block 905. Since the thread directions of the first threaded rod 904 and the second threaded rod 906 are opposite, The threaded moving block 907 realizes synchronous and stable movement toward or away from each other when the two threaded rods rotate. The limit plate 908 above the moving block 907 moves with it, and the limit block 909 at its bottom slides in the limit groove 910 to ensure the accuracy of the moving direction of the limit plate 908. The photoelectric sensor 911 located above the limit plate 908 detects the light blocking of the material in real time. When it is detected that the material is in place, the second motor 903 stops rotating according to the preset program, so that the limit plate 908 and the moving block 907 stop moving, and the material is accurately positioned at the predetermined position. After the positioning is completed, the material will enter the extruder at the accurate initial position, providing accurate material for the subsequent power capacitor aluminum shell processing. Supply, ensuring high precision and high quality of the entire processing process, effectively improving production efficiency, and reducing product quality problems and equipment failures caused by inaccurate or unstable feeding. Moreover, in the whole process, the multiple groups of bottom pads 2 symmetrically distributed at the bottom of the bracket 1 ensure the stability of the device, avoiding shaking or tilting of the device due to factors such as conveyor belt operation vibration and change of material movement center of gravity, reducing the occurrence of problems such as material falling and conveyor belt deviation. The model of the hydraulic cylinder 7 is CDM2B25, the model of the first motor 802 is Y315S-2, and the model of the second motor 903 is YE2-132S-4, thus completing the use process of a feeding device of an extruder for processing aluminum shells of power capacitors.
