DETAILED DESCRIPTION

[0025] 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.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-Figure 3 The present invention provides an automatic weighing batching transportation transmission device, comprising:

[0028] The weighing device 1 is provided with a weighing platform 11;

[0029] The conveying guide rail 2 has a weighing through hole 21 on its bottom wall along the gravity direction, and the weighing through hole 21 is located above the weighing platform 11;

[0030] A plurality of moving parts 3 are slidably arranged on the conveying guide rail 2. An assembly through hole 31 is opened on the moving part 3 along the gravity direction. The assembly through hole 31 is used to place the material pipe 4. When the material pipe 4 is located in the middle of the assembly through hole 31, there is a gap between the side wall of the assembly through hole 31 and the side wall of the material pipe 4. When the assembly through hole 31 is located above the weighing through hole 21, the material pipe 4 can fall onto the weighing platform 11.

[0031] The driving mechanism is used to drive the moving member 3 to slide forward or backward along the conveying guide rail 2. When the moving member 3 slides forward, it can push the material pipe 4 to slide along the conveying guide rail 2.

[0032] By opening a weighing through hole 21 on the conveying guide rail 2 and an assembly through hole 31 on the moving part 3, it is only necessary to place the material tube 4 loaded with materials into the assembly through hole 31, and drive the moving part 3 to slide along the conveying guide rail 2 through the driving mechanism. When the assembly through hole 31 loaded with the material tube 4 is located above the weighing through hole 21, the material tube 4 can automatically fall onto the weighing platform 11, and through the backward sliding of the moving part 3, any contact objects are removed from the side wall of the material tube 4, so that the weighing platform 11 performs material weighing operations on the material tube 4. After the weighing is completed, the material tube 4 continues to slide along the conveying guide rail 2 as driven by the driving mechanism. It can be combined with an external loading device. It is only necessary to place batches of material tubes 4 into multiple assembly through holes 31 respectively, so as to realize automatic weighing and transportation operations of materials. It can be adapted to the application of automated assembly lines, effectively reduce the workload of experimenters, and improve experimental efficiency.

[0033] In one embodiment of the present invention, a groove 32 is provided at one end of the assembly through hole 31, and the two sides of the groove 32 are inclined toward the two side walls of the slideway on the conveying guide rail 2 with the center line of the slideway on the conveying guide rail 2 as the intersection point, and the two side walls of the groove 32 are used to abut against the side walls of the material pipe 4.

[0034] By providing a pair of grooves 32 with symmetrically inclined side walls, when the moving member 3 slides forward, the side walls of the groove 32 contact the material pipe 4 and can push the material pipe 4 to move, and the pair of side walls of the groove 32 can also play a guiding role so that the material pipe 4 is located at the center of the conveying channel on the conveying guide rail 2, thereby avoiding interference between the material pipe 4 and the side walls of the conveying guide rail 2 when pushing the material pipe 4 to move, so that the moving member 3 can slide smoothly in the sliding part on the conveying guide rail 2.

[0035] In one embodiment of the present invention, the conveying guide rail 2 includes a conveying section 22 and a weighing section 23 that are connected. The conveying section 22 is provided with an opening, and the weighing section 23 is arranged at the opening. The weighing section 23 is provided with a weighing through hole 21, and the bottom walls of the weighing section 23 located on both sides of the weighing through hole 21 are symmetrically provided with slopes 24, and the two slopes 24 are respectively located on both sides of the weighing platform 11. The high end of the slope 24 is located in the same plane as the bottom wall of the conveying section 22, and the low end of the slope 24 faces the weighing platform 11 and is not higher than the top surface of the weighing platform 11. The distance between the low end of the slope 24 and the edge of the weighing platform 11 is less than the diameter of the material pipe 4.

[0036] The slope 24 can play a role in guiding transition, so that the material pipe 4 can move stably when entering or moving out of the weighing through hole 21 .

[0037] In one embodiment of the present invention, a pair of first ear plates 33 are provided at one end of the moving member 3, and a second ear plate 34 is provided at the other end of the moving member 3. The pair of first ear plates 33 of the moving member 3 are used to be hinged with the second ear plate 34 of another moving member 3.

[0038] The arrangement of a pair of first ear plates 33 and a second ear plate 34 can facilitate the articulation of a plurality of moving members 3 , so as to facilitate the weighing of batches of material tubes 4 .

[0039] In one embodiment of the present invention, the driving mechanism includes a pair of annular belts 5, which are rotatably disposed on both sides of the moving part 3 through a motor 6, and the outer surface of the annular belts 5 is used to abut against the side wall of the moving part 3. The annular belts 5 are made of elastic material.

[0040] The motor 6 rotates by driving the gear, and the gear engages with the tooth groove on the inner surface of the annular belt 5 to drive the annular belt 5 to rotate. The rotation of a pair of annular belts 5 generates friction with the moving member 3, thereby driving the moving member 3 to slide along the conveying guide rail 2.

[0041] In one embodiment of the present invention, the movable part 3 includes a restraining ring 35 and a pair of side plates 36 fixedly connected to the bottom surface of the restraining ring 35, the assembly through hole 31 is opened in the restraining ring 35, the restraining ring 35 is placed on the top of the two side walls of the conveying guide rail 2, and the side plate 36 slides in the slide of the conveying guide rail 2.

[0042] The restraining ring 35 is used to make contact with the endless belt 5 , and the side plate 36 is used to improve the stability with the conveying guide rail 2 .

[0043] In one embodiment of the present invention, the conveying guide rail 2 is a closed ring structure.

[0044] The conveying guide rail 2 of the closed loop structure cooperates with a plurality of moving parts 3 to carry out continuous batch weighing of material tubes 4 .

[0045] In one embodiment of the present invention, a supporting platform 7 is further included for assembling the weighing device 1, the conveying guide rail 2 and the driving mechanism.

[0046] In one embodiment of the present invention, a lifting frame 8 is provided between the conveying guide rail 2 and the driving mechanism and the supporting platform 7 .
