The telescopic device 400 is used to drive the elastic tube 240 to expand away from the end of the connecting tube 210. A guide ring 241 is circumferentially provided on the inner wall of the elastic tube 240. The guide ring 241 is provided at a position away from the connecting tube 210. The diameter of the guide ring 241 gradually increases in the direction away from the connecting tube 210. A clamping space 242 for clamping a material receiving tube 600 is provided between the guide ring 241 and the end of the elastic tube 240.

[0021] In this embodiment, the hose 200, the connecting tube 210 and the elastic tube 240 are mainly used for conveying fluid materials such as gasoline, etc. In other embodiments, granular or other pumpable flowing materials can also be conveyed through the hose 200, the connecting tube 210 and the elastic tube 240; the material conveying source is provided with a conveying mechanism such as a pump body for conveying the material.

[0022] By adopting the above technical solution, by adopting the setting of the telescopic device 400, the telescopic device 400 can drive the end of the elastic tube 240 to expand, so that the elastic tube 240 can be applied to the material receiving tube 600 of different specifications, thereby improving the applicability of the material quantitative loading system; and by adopting the setting of the elastic tube 240, the elastic tube 240 can be applied to some special-shaped material receiving tubes 600, thereby further improving the applicability of the elastic tube 240; by adopting the setting of the elastic tube 240, the elastic tube 240 can be sleeved on the outer wall of the material receiving tube 600 by its own elastic force, thereby indirectly improving the sealing effect between the elastic tube 240 and the material receiving tube 600; by adopting the guide ring By setting 241 and the clamping space 242, when the receiving tube 600 is clamped in the clamping space 242, the material can be guided by the guide ring 241, thereby preventing the material from accumulating in the gap between the elastic tube 240 and the receiving tube 600, and preventing the material from leaking along the gap between the elastic tube 240 and the receiving tube 600, so that the material is fed completely and the feeding effect of the material is improved; by adopting the setting of the driving device 300, the driving device 300 can drive the connecting tube 210 to drive the elastic tube 240 to move to the position of the receiving tube 600, so that the elastic tube 240 can be suitable for receiving tubes 600 at different positions, thereby further improving the applicability of the material quantitative loading system.

[0023] Combination Figures 1 to 4 The telescopic device 400 includes a plurality of cylinders 410 and a plurality of connecting rods 420. The plurality of cylinders 410 are evenly distributed along the circumference of 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 plurality of connecting rods 420 are evenly distributed along the circumference of the elastic tube 240. A connecting piece 430 is provided at the other end of the connecting rod 420. The connecting piece 430 is used to detachably connect the connecting rod 420 to the output end of the cylinder 410.

[0024] In this embodiment, six cylinders 410 are provided, and six connecting rods 420 are provided. The six connecting rods 420 are provided in a one-to-one correspondence with the six cylinders 410 .

[0025] By adopting the above technical solution, when it is necessary to drive the end of the elastic tube 240 to expand, the cylinder 410 drives the connecting rod 420 to move. Since multiple connecting rods 420 are arranged circumferentially on the outer wall of the elastic tube 240, multiple connecting rods 420 can drive the elastic tube 240 to expand, so that the elastic tube 240 can be suitable for receiving tubes 600 of different specifications. By adopting a simple structure of the cylinder 410 and the connecting rod 420, the effect of expanding the end of the elastic tube 240 is improved; by detachably connecting the connecting rod 420 to the output end of the cylinder 410, it is convenient to disconnect 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 sleeve of the elastic tube 240 and the receiving tube 600.

[0026] Combination Figures 1 to 4 The connecting member 430 includes an electromagnet 431 and a metal plate 432. The electromagnet 431 is hinged on the driving end of the cylinder 410. The metal plate 432 is arranged at the end of the connecting rod 420 away from the elastic tube 240. The electromagnet 431 is used to adsorb or de-adsorb the metal plate 432. In this embodiment, the metal plate 432 is set as a stainless steel plate.

[0027] By adopting the above technical solution, when it is necessary to connect the connecting rod 420 with the driving end of the cylinder 410, the electromagnet 431 is energized so that the electromagnet 431 can be adsorbed with the metal plate 432, thereby connecting the connecting rod 420 with 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 deenergized so that the electromagnet is detached from the metal plate 432. At this time, the elastic tube 240 can be mounted on the material receiving tube 600 by its own elastic force.

[0028] Combination Figures 1 to 4 A slot 433 is provided on the electromagnet 431, and an insert block 434 for plugging into or out of the slot 433 is provided on the metal plate 432; in the present embodiment, the slot 433 is arranged in a rectangular shape, the rectangular slot 433 is arranged in the middle of the electromagnet 431, the insert block 434 is arranged in cooperation with the rectangular slot 433, and the insert block 434 is arranged in the middle of the metal plate 432.

[0029] By adopting the above technical solution, the setting of the plug block 434 and the slot 433 can play a positioning effect on the installation between the electromagnet 431 and the metal plate 432, preventing the installation deviation between the electromagnet 431 and the metal plate 432, thereby improving the installation effect between the electromagnet 431 and the metal plate 432.

[0030] Combination Figures 1 to 4The cylinder 410 is hingedly arranged on the connecting pipe 210 , and a rotating mechanism 500 is arranged on the connecting pipe 210 and at the position where each cylinder 410 is located. The rotating mechanism 500 is used to drive the cylinder 410 to rotate in the vertical direction at the hinge point of the connecting pipe 210 .

[0031] By adopting the above technical solution, by hingedly setting the cylinder 410 on the connecting pipe 210, the hinge point of the cylinder 410 on the connecting pipe 210 is driven to rotate by the rotating mechanism 500, so that the driving end of the cylinder 410 can be close to or away from the elastic tube 240. When the driving end of the cylinder 410 is extended or retracted, the moving stroke of the connecting rod 420 driven by the cylinder 410 is indirectly extended, thereby further expanding the end of the elastic tube 240, thereby further making the elastic tube 240 suitable for receiving tubes 600 of different specifications, and further improving the applicability of the elastic tube 240.

[0032] 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 arranged on the outer wall of the connecting pipe 210, the rotating shaft 520 is arranged 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 arranged on the fixed plate 510. The rotating motor 530 is used to drive the rotating shaft 520 to drive the cylinder 410 to rotate.

[0033] By adopting the above technical solution, the rotating shaft 520 is driven to rotate by the rotating motor 530, so that the rotating shaft 520 drives the cylinder 410 to rotate, thereby causing the cylinder 410 to rotate at the hinge point on the connecting pipe 210. By adopting the setting of the rotating motor 530, its structure is simple and the driving effect of the rotation of the cylinder 410 is improved.

[0034] Combination Figures 1 to 4 A intercepting groove 243 is provided on the guide ring 241 along the axial direction of the connecting pipe 210 , the top of the intercepting groove 243 is provided as an open end penetrating the guide ring 241 , and the bottom of the intercepting groove 243 is provided as a closed end.

[0035] In this embodiment, the cross section of the intercepting groove 243 is arranged in a "U" shape.

[0036] By adopting the above technical solution and the setting of the intercepting groove 243, when the elastic tube 240 completes feeding and is separated from the receiving tube 600, part of the material can move downward along the inner wall of the connecting tube 210 and the elastic tube 240, and finally enter the intercepting groove 243 for temporary storage, so as to facilitate the operator to subsequently handle the remaining material in the intercepting groove 243 and prevent the material from falling to the ground or other locations and affecting the ground or other environment.

[0037] Combination Figures 1 to 4An arc rod 421 is provided on the outer wall of the elastic tube 240 and at the position where each connecting rod 420 is located. The arc rod 421 is arranged along the circumference of the elastic tube 240, and the connecting rod 420 is connected to the arc rod 421. The connecting rod 420 is connected to the outer wall of the elastic tube 240 through the arc rod 421.

[0038] By adopting the above technical solution and the setting of the arc rod 421, when the cylinder 410 drives the connecting rod 420 to move, the connecting rod 420 can drive the arc rod 421 to move, thereby indirectly increasing the connection area between the connecting rod 420 and the elastic tube 240, thereby further improving the effect of expanding the end of the elastic tube 240.

[0039] Combination Figures 1 to 4 The driving device 300 includes a sliding plate 310, a first electric cylinder 320 and a second electric cylinder 330. The sliding plate 310 is slidably set on the column 100 along the height direction of the column 100. The first electric cylinder 320 is set on the column 100. The sliding plate 310 is connected to the driving end of the first electric cylinder 320. The second electric cylinder 330 is set on the sliding plate 310, and the connecting pipe 210 is connected to the driving end of the second electric cylinder 330.

[0040] In this embodiment, a sliding ring 311 which is sleeved on and slidably connected to the column 100 is fixedly provided on the sliding plate 310 , and the sliding plate 310 is slidably connected to the column 100 via the sliding ring 311 .

[0041] By adopting the above technical solution, the sliding plate 310 is driven to move by the first electric cylinder 320, so that the sliding plate 310 can drive the second electric cylinder 330 to move up and down, thereby the second electric cylinder 330 drives the connecting tube 210 to move up and down, and the connecting tube 210 is driven to move by the second electric cylinder 330, so that the second electric cylinder 330 can drive the connecting tube 210 to move closer to or away from the column 100, thereby realizing the adjustment of the connecting tube 210 in the height direction and the horizontal direction, increasing the moving range of the connecting tube 210, thereby indirectly increasing the moving range of the elastic tube 240.

[0042] The present application also provides an automatic loading method, which uses the material quantitative loading system of any one of the above embodiments, and the automatic loading method includes: The elastic tube 240 is driven to expand by the telescopic device 400; The driving device 300 drives the elastic tube 240 to be sleeved on the material receiving tube 600 so that the material receiving tube 600 is clamped in the clamping space 242. At this time, the material can be transported to the elastic tube 240 along the hose 200 and the connecting tube 210, and guided into the material receiving tube 600 through the guide ring 241 in the elastic tube 240.

[0043] The automatic loading method provided in the embodiment of the present application adopts a material quantitative loading system. When material transportation is required, the sliding plate 310 is driven to rise and fall by the first electric cylinder 320, and the connecting tube 210 is driven to move in the horizontal direction by the second electric cylinder 330, so as to adjust the positions of the connecting tube 210 and the elastic tube 240. When the elastic tube 240 moves to the position where the material receiving tube 600 is located, the electromagnet 431 is energized so that the electromagnet 431 can be adsorbed with the metal plate 432. At this time, the rotating shaft 520 is driven by the rotating motor 530 to drive the cylinder 410 to rotate, and the connecting rod 420 is driven to move by the driving end of the cylinder 410, so that the elastic tube 240 is expanded. At this time, the elastic tube 240 is able to expand, and the elastic tube 240 is driven to move again by the first electric cylinder 320 and the second electric cylinder 330. The elastic tube 240 is moved so that the elastic tube 240 is sleeved on the material receiving tube 600. At this time, the edge of the material receiving tube 600 can be clamped in the clamping space 242, the electromagnet 431 is powered off and is separated from the metal plate 432. The elastic tube 240 can be sleeved on the material receiving tube 600 by its own elastic force, and the material is transported through the hose 200, the connecting tube 210 and the elastic tube 240. When the material moves to the position where the guide ring 241 is located, the guide ring 241 can guide the material into the material receiving tube 600. When the material is transported, the material remaining on the inner walls of the connecting tube 210 and the elastic tube 240 can enter the intercepting groove 243 for temporary storage. By adopting the setting of the elastic tube 240, the elastic tube 240 can be suitable for material receiving tubes 600 of different diameters, thereby improving the applicability of the material quantitative loading system.
