[0003] The material quantitative loading system of the related technology includes a column, a conveying pipe and a drive mechanism. The drive mechanism and the conveying pipe are both set on the column. The drive mechanism drives the conveying pipe to move, so that the conveying pipe connects with the receiving pipe of the equipment to be loaded, so that the material can be transported through the conveying pipe to the receiving pipe, thereby realizing the loading of the equipment to be loaded.

[0004] However, different receiving pipes have different diameters, which means that the same conveying pipe cannot be used for receiving pipes of different diameters, reducing the applicability of the material quantitative loading system. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a material quantitative loading system to solve the technical problem that the conveying pipes of related technologies cannot be applied to receiving pipes of different diameters.

[0006] The above-mentioned objective of this invention is achieved through the following technical solutions:

An elastic tube is provided at the end of the connecting pipe away from the hose. A telescopic device is provided on the connecting pipe and is used to drive the end of the elastic tube away from the connecting pipe to expand. A guide ring is circumferentially arranged on the inner wall of the elastic tube. The guide ring is located away from the connecting pipe, and the diameter of the guide ring gradually increases in the direction away from the connecting pipe. There is a snap-fit ​​space between the guide ring and the end of the elastic tube for the receiving pipe to snap into place.

[0008] In some embodiments, the telescopic device includes a plurality of cylinders and a plurality of connecting rods. The plurality of cylinders are evenly distributed circumferentially along the outer wall of the connecting tube. One end of each connecting rod is connected to the outer wall of the elastic tube. The plurality of connecting rods are evenly distributed circumferentially along the elastic tube. The other end of each connecting rod is provided with a connector for detachably connecting the connecting rod to the output end of the cylinder.

[0009] In some embodiments, the connector includes an electromagnet and a metal plate, the electromagnet being hinged to the drive end of the cylinder, the metal plate being disposed at the end of the connecting rod away from the elastic tube, and the electromagnet being used to attract or detach from the metal plate.

[0010] In some embodiments, the electromagnet is provided with a slot, and the metal plate is provided with a plug for inserting into or disengaging from the slot.

[0011] In some embodiments, the cylinder is hinged to the connecting pipe, and a rotating mechanism is provided on the connecting pipe at the location of each cylinder. The rotating mechanism is used to drive the cylinder to rotate vertically at the hinge point of the connecting pipe.

[0012] In some embodiments, the rotating mechanism includes a fixed plate, a rotating shaft, and a rotating motor. The fixed plate is disposed on the outer wall of the connecting pipe, the rotating shaft is disposed on the cylinder, the rotating shaft passes through and is rotatably connected to the fixed plate, and the rotating motor is disposed on the fixed plate. The rotating motor is used to drive the rotating shaft to rotate the cylinder.

[0013] In some embodiments, a flow-blocking groove is provided on the guide ring along the axial direction of the connecting pipe, the top of the flow-blocking groove is configured as an open end that penetrates the guide ring, and the bottom of the flow-blocking groove is configured as a closed end.

[0014] In some embodiments, an arc-shaped rod is provided on the outer wall of the elastic tube at the location of each connecting rod. The arc-shaped rod is arranged along the circumference of the elastic tube, and the connecting rod is connected to the arc-shaped rod. The connecting rod is connected to the outer wall of the elastic tube through the arc-shaped rod.

[0015] In some embodiments, the driving device includes a sliding plate, a first electric cylinder, and a second electric cylinder. The sliding plate is slidably disposed on the column along the height direction of the column. The first electric cylinder is disposed on the column. The sliding plate is connected to the driving end of the first electric cylinder. The second electric cylinder is disposed on the sliding plate. The connecting pipe is connected to the driving end of the second electric cylinder.

[0016] On the other hand, this application provides an automatic loading method using the aforementioned material quantitative loading system, the automatic loading method comprising:

[0017] The elastic tube is expanded by the telescopic device;

[0018] The drive device drives the elastic tube to be sleeved on the receiving tube, so that the receiving tube is snapped into the snapping space. At this time, the material can be transported along the hose and the connecting tube to the elastic tube, and guided into the receiving tube by the guide ring in the elastic tube.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] By employing a telescopic device, the end of the elastic tube can be expanded, allowing it to be used with receiving tubes of different specifications, thus improving the applicability of the material quantitative loading system. Furthermore, the elastic tube allows it to be used with some irregularly shaped receiving tubes, further enhancing its applicability. The elastic tube's own elasticity allows it to fit snugly against the outer wall of the receiving tube, indirectly improving the sealing effect between them. The use of a guide ring and a snap-fit ​​space ensures that when the receiving tube is snapped into the snap-fit ​​space, the material is guided by the guide ring, preventing material accumulation in the gap between the elastic tube and the receiving tube, and preventing leakage along this gap, ensuring complete material feeding and improving the feeding efficiency. Finally, the drive device allows the connecting tube to move the elastic tube to the location of the receiving tube, enabling it to be used with receiving tubes in different positions, further improving the applicability of the material quantitative loading system.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Combination Figures 1 to 4 This invention discloses a material quantitative loading system, comprising a column 100, a hose 200, and a drive device 300. One end of the hose 200 is connected to a material conveying source, and the other end is provided with a connecting pipe 210. A flow meter 220 and an on / off valve 230 are sequentially arranged on the connecting pipe 210 in a direction away from the hose 200. The drive device 300 is mounted on the column 100 and is used to drive the connecting pipe 210 to the position of the receiving pipe 600, away from the hose 200. An elastic tube 240 is provided at the end of the 0, and a telescopic device 400 is provided on the connecting tube 210. The telescopic device 400 is used to drive the end of the elastic tube 240 away from the connecting tube 210 to expand. A guide ring 241 is provided circumferentially on the inner wall of the elastic tube 240. The guide ring 241 is located away from the connecting tube 210. The diameter of the guide ring 241 gradually increases in the direction away from the connecting tube 210. There is a snapping space 242 between the guide ring 241 and the end of the elastic tube 240 for snapping the receiving tube 600.

[0028] In this embodiment, the hose 200, connecting pipe 210, and elastic pipe 240 are mainly used for conveying fluid materials such as gasoline. In other embodiments, the hose 200, connecting pipe 210, and elastic pipe 240 can also be used to convey granular or other pumpable materials. The material conveying source is provided with a conveying mechanism such as a pump body for conveying materials.

[0029] By adopting the above technical solution, and by using the telescopic device 400, the telescopic device 400 can drive the end of the elastic tube 240 to expand, making the elastic tube 240 suitable for receiving tubes 600 of different specifications, thereby improving the applicability of the material quantitative loading system; and by using the elastic tube 240, the elastic tube 240 can be used for some irregularly shaped receiving tubes 600, thereby further improving the applicability of the elastic tube 240; by using the elastic tube 240, the elastic tube 240 can be fitted onto the outer wall of the receiving tube 600 by its own elasticity, thereby indirectly improving the sealing effect between the elastic tube 240 and the receiving tube 600; by using a guide ring The arrangement of 241 and the snap-fit ​​space 242 allows material to be guided by the guide ring 241 when the receiving tube 600 is snapped into the snap-fit ​​space 242. This prevents material from accumulating in the gap between the elastic tube 240 and the receiving tube 600, and also prevents material from leaking along the gap between the elastic tube 240 and the receiving tube 600, ensuring complete material feeding and improving the material feeding effect. By using the drive device 300, the drive device 300 can drive the connecting tube 210 to move the elastic tube 240 to the position of the receiving tube 600, making the elastic tube 240 suitable for receiving tubes 600 in different positions, thereby further improving the applicability of the material quantitative loading system.

[0030] Combination Figures 1 to 4 The telescopic device 400 includes multiple cylinders 410 and multiple connecting rods 420. The multiple cylinders 410 are evenly distributed around the outer wall of the connecting tube 210. One end of the connecting rod 420 is connected to the outer wall of the elastic tube 240. The multiple connecting rods 420 are evenly distributed around the circumference of the elastic tube 240. The other end of the connecting rod 420 is provided with a connector 430. The connector 430 is used to detachably connect the connecting rod 420 to the output end of the cylinder 410.

[0031] In this embodiment, six cylinders 410 and six connecting rods 420 are provided, with each of the six connecting rods 420 corresponding to one of the six cylinders 410.

[0032] By adopting the above technical solution, when it is necessary to expand the end of the elastic tube 240, the connecting rod 420 is moved by the cylinder 410. Since multiple connecting rods 420 are arranged circumferentially on the outer wall of the elastic tube 240, the multiple connecting rods 420 can drive the elastic tube 240 to expand, so that the elastic tube 240 can be used with receiving tubes 600 of different specifications. The simple structure of the cylinder 410 and connecting rod 420 improves the effect of expanding the end of the elastic tube 240. By detachably connecting the connecting rod 420 to the output end of the cylinder 410, it is easy to disengage the connecting rod 420 from the cylinder 410 when the end of the elastic tube 240 is sleeved on the receiving tube 600, so as to prevent the driving force of the cylinder 410 from affecting the sleeved elastic tube 240 and the receiving tube 600.

[0033] Combination Figures 1 to 4 The connector 430 includes an electromagnet 431 and a metal plate 432. The electromagnet 431 is hinged to the drive end of the cylinder 410, and the metal plate 432 is disposed at the end of the connecting rod 420 away from the elastic tube 240. The electromagnet 431 is used to attract or detach from the metal plate 432. In this embodiment, the metal plate 432 is a stainless steel plate.

[0034] By adopting the above technical solution, when it is necessary to connect the connecting rod 420 to the driving end of the cylinder 410, the electromagnet 431 is energized so that the electromagnet 431 can be attracted to the metal plate 432, thereby connecting the connecting rod 420 to the driving end of the cylinder 410. When it is necessary to disconnect the connecting rod 420 from the driving end of the cylinder 410, the electromagnet 431 is de-energized so that the electromagnet is disconnected from the metal plate 432. At this time, the elastic tube 240 can be sleeved on the receiving tube 600 by its own elasticity.

[0035] Combination Figures 1 to 4 The electromagnet 431 is provided with a slot 433, and the metal plate 432 is provided with a plug 434 for inserting into or disengaging from the slot 433. In this embodiment, the slot 433 is rectangular and is located in the middle of the electromagnet 431. The plug 434 is configured to cooperate with the rectangular slot 433 and is located in the middle of the metal plate 432.

[0036] By adopting the above technical solution, the use of insert block 434 and slot 433 can achieve the positioning effect between electromagnet 431 and metal plate 432, prevent the installation of electromagnet 431 and metal plate 432 from being misaligned, thereby improving the installation effect between electromagnet 431 and metal plate 432.

[0037] Combination Figures 1 to 4The cylinder 410 is hinged on the connecting pipe 210. A rotating mechanism 500 is provided on the connecting pipe 210 at the location of each cylinder 410. The rotating mechanism 500 is used to drive the cylinder 410 to rotate vertically at the hinge point of the connecting pipe 210.

[0038] By adopting the above technical solution, the cylinder 410 is hinged to the connecting pipe 210, and the hinge point of the cylinder 410 on the connecting pipe 210 is driven to rotate by the rotating mechanism 500. This allows the driving end of the cylinder 410 to approach or move away from the elastic tube 240. When the driving end of the cylinder 410 extends or retracts, the travel of the connecting rod 420 driven by the cylinder 410 is indirectly extended, thereby further expanding the end of the elastic tube 240. This further makes the elastic tube 240 suitable for receiving pipes 600 of different specifications, and further improves the applicability of the elastic tube 240.

[0039] Combination Figures 1 to 4 The rotating mechanism 500 includes a fixed plate 510, a rotating shaft 520, and a rotating motor 530. The fixed plate 510 is disposed on the outer wall of the connecting pipe 210, the rotating shaft 520 is disposed on the cylinder 410, the rotating shaft 520 passes through and is rotatably connected to the fixed plate 510, and the rotating motor 530 is disposed on the fixed plate 510. The rotating motor 530 is used to drive the rotating shaft 520 to drive the cylinder 410 to rotate.

[0040] By adopting the above technical solution, the rotating shaft 520 is driven to rotate by the rotating motor 530, which in turn drives the cylinder 410 to rotate, thereby causing the hinge point of the cylinder 410 on the connecting pipe 210 to rotate. The use of the rotating motor 530 simplifies the structure and improves the driving effect on the rotation of the cylinder 410.

[0041] Combination Figures 1 to 4 A flow intercepting groove 243 is provided on the guide ring 241 along the axial direction of the connecting pipe 210. The top of the flow intercepting groove 243 is set as an open end that penetrates the guide ring 241, and the bottom of the flow intercepting groove 243 is set as a closed end.

[0042] In this embodiment, the cross-section of the intercepting channel 243 is U-shaped.

[0043] By adopting the above technical solution and by setting up the intercepting trough 243, when the elastic tube 240 completes the feeding and separates from the receiving tube 600, some material can move down along the inner wall of the connecting tube 210 and the elastic tube 240, and finally enter the intercepting trough 243 for temporary storage. This facilitates the subsequent handling of the material remaining in the intercepting trough 243 by the operator, and prevents the material from falling to the ground or other locations, which could affect the ground or other environments.

[0044] Combination Figures 1 to 4An arc-shaped rod 421 is provided on the outer wall of the elastic tube 240 at the location of each connecting rod 420. The arc-shaped rod 421 is arranged along the circumference of the elastic tube 240. The connecting rod 420 is connected to the arc-shaped rod 421 and is connected to the outer wall of the elastic tube 240 through the arc-shaped rod 421.

[0045] By adopting the above technical solution and by using the arc-shaped rod 421, when the cylinder 410 drives the connecting rod 420 to move, the connecting rod 420 can drive the arc-shaped rod 421 to move, thereby indirectly increasing the connection area between the connecting rod 420 and the elastic tube 240, thereby further improving the end expansion effect of the elastic tube 240.

[0046] Combination Figures 1 to 4 The drive device 300 includes a sliding plate 310, a first electric cylinder 320 and a second electric cylinder 330. The sliding plate 310 is slidably disposed on the column 100 along the height direction of the column 100. The first electric cylinder 320 is disposed on the column 100. The sliding plate 310 is connected to the drive end of the first electric cylinder 320. The second electric cylinder 330 is disposed on the sliding plate 310. The connecting pipe 210 is connected to the drive end of the second electric cylinder 330.

[0047] In this embodiment, a sliding ring 311 is fixedly provided on the sliding plate 310 and slidably connected to the column 100. The sliding plate 310 is slidably connected to the column 100 through the sliding ring 311.

[0048] By adopting the above technical solution, the sliding plate 310 is moved by the first electric cylinder 320, which in turn drives the second electric cylinder 330 to rise and fall. This causes the second electric cylinder 330 to move the connecting pipe 210 up and down. By driving the connecting pipe 210 to move, the second electric cylinder 330 can move the connecting pipe 210 closer to or further away from the column 100, thereby achieving adjustment of the height and horizontal direction of the connecting pipe 210, increasing the range of movement of the connecting pipe 210, and thus indirectly increasing the range of movement of the elastic tube 240.

[0049] This application also provides an automatic loading method, employing the material quantitative loading system of any of the above embodiments. The automatic loading method includes:

[0050] The elastic tube 240 is expanded by the telescopic device 400;

[0051] The drive device 300 drives the elastic tube 240 to be sleeved on the receiving tube 600 so that the receiving tube 600 is snapped into the snapping space 242. At this time, the material can be transported along the hose 200 and the connecting tube 210 to the elastic tube 240 and guided into the receiving tube 600 through the guide ring 241 in the elastic tube 240.

[0052] The automatic loading method provided in this application embodiment employs a material quantitative loading system. When material transportation is required, the sliding plate 310 is raised and lowered by the first electric cylinder 320, and the connecting pipe 210 is moved horizontally by the second electric cylinder 330, thereby adjusting the positions of the connecting pipe 210 and the elastic pipe 240. When the elastic pipe 240 moves to the position of the receiving pipe 600, the electromagnet 431 is energized, allowing the electromagnet 431 to attract the metal plate 432. At this time, the rotating shaft 520 is driven by the rotating motor 530 to rotate the cylinder 410, and the driving end of the cylinder 410 drives the connecting rod 420 to move, thereby expanding the elastic pipe 240. The elastic pipe 240 is then expanded, and the first electric cylinder 320 and the second electric cylinder 330 are used to drive the elastic pipe 240 to move again. The movement causes the elastic tube 240 to be fitted onto the receiving tube 600. At this time, the edge of the receiving tube 600 can be engaged in the engagement space 242. When the electromagnet 431 is de-energized, it disengages from the metal plate 432. The elastic tube 240 can be fitted onto the receiving tube 600 by its own elasticity. The material is conveyed through the hose 200, connecting pipe 210 and elastic tube 240. When the material moves to the position of the guide ring 241, the guide ring 241 can guide the material into the receiving tube 600. When the material is conveyed, the material remaining on the inner wall of the connecting pipe 210 and the elastic tube 240 can enter the intercepting groove 243 for temporary storage. By using the elastic tube 240, it can be adapted to receiving tubes 600 of different diameters, thereby improving the applicability of the material quantitative loading system.

[0053] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
