Description

Technical Field

[0001] The invention relates to the technical field of material spreading robots, in particular to an automatic material spreading robot for loading plastic textile raw materials. Background Art

[0002] The raw materials of plastic textiles are granular, which will be manufactured into flat braided ropes only after being melted. Before molding, the materials need to be filled into the material box first. However, since the position of the feeding pipe is fixed, the bulk material will eventually form a raised pile. From the perspective of raw material ratio, the amount of material in the material box needs to be controlled. The scale of the cylindrical tank is generally located on the side wall. Therefore, if you want to know the amount of material that has been added, you need to flatten it manually. This process is called "flattening".

[0003] The existing Chinese authorized invention patent document CN116395430B discloses an automatic material spreading robot for loading plastic textile raw materials, in which the material is pushed outward by a designed anti-stacking auger conveying and flattening mechanism to prevent the material from piling up into a raised pile. However, the raw materials are in a granular state, and it is difficult to arrange them as closely as a cube when stacking. Due to the shape differences between the particles, they cannot be arranged as closely as a sphere when stacking, and more gaps will be generated. Although the existing structure can prevent the material from piling up into a pile, it cannot reduce the gaps between the materials, making it difficult to accurately control the amount of material.

DETAILED DESCRIPTION

[0028] 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.

[0029] Example 1: Please refer to Figure 1 - Figure 5 , an automatic material spreading manipulator for loading plastic textile raw materials shown in the figure, including a rotating tube 1 rotatably installed on the outside of a feeding tube, and also including a bracket 2 fixed on the rotating tube 1, on which a rotating part 3 for driving the rotating tube 1 to rotate is installed; and a track frame 4 fixed at the bottom of the bracket 2, on which a discharging tube 5 is slidably installed, and a spring tube 6 is fixedly connected between the discharging tube 5 and the feeding tube, and the spring tube 6 has a deformation capacity to meet the requirements that the discharging tube 5 can normally transmit materials when moving in the track frame 4, and a material mixing rocker 7 is installed at the bottom of the bracket 2, and the discharging tube 5 is driven to move in the track frame 4 by the material mixing rocker 7; and a knocking part 8 fixed on the outside of the track frame 4, through which the knocking part 8 knocks the inner wall of the collecting box to reduce the material accumulation gap;

[0030] In this solution, the material discharge pipe is fixed above the material collection box, and the material enters the material collection box through the material discharge pipe. The rotating part 3 provides power to drive the bracket 2 to rotate in the material collection box, and the material leveling rocker arm 7 drives the discharge pipe 5 in the track frame 4 to move accordingly, so that during the rotation process, the material can be discharged evenly in the material collection box to avoid the phenomenon of material pile;

[0031] It should be noted that: in this solution, when unloading materials, the knocking part 8 can also be triggered to knock on the inner wall of the aggregate box and vibrate the piled materials in the aggregate box. This can effectively vibrate and reorganize the materials in some stacking gaps and reduce the gaps between the materials, thereby improving the measurement accuracy when collecting materials.

[0032] For further information, see Figure 3 and Figure 4 A moving opening 9 is provided on the track frame 4, and an adjusting rod 10 is fixed on the discharge pipe 5 and is slidably connected with the moving opening 9. The adjusting rod 10 is adapted to the knocking part 8, and the adjusting rod 10 slides along the moving opening 9, so that the discharge pipe 5 is more stable when moving in the track frame 4;

[0033] Also, see Figure 7 - Fig. 9 The knocking part 8 includes an inclined rod 11 fixed to the outside of the track frame 4, a force storage plate 12 is slidably sleeved on the outside of the inclined rod 11, a knocking protrusion 13 is fixed to the outer end of the force storage plate 12, a force storage spring 14 is sleeved on the outside of the inclined rod 11 and abuts against the force storage plate 12, and a contact piece 15 that contacts the adjustment rod 10 is installed on the side of the force storage plate 12 close to the track frame 4;

[0034] The contact member 15 includes a contact plate 16 rotatably mounted on the force storage plate 12 , a butt plate 17 abutting against the contact plate 16 is fixed on the force storage plate 12 , and magnetic blocks that are magnetically attracted to each other are installed between the contact plate 16 and the butt plate 17 .

[0035] The principle of the knocking part 8 knocking on the inner wall of the collecting box is as follows: first, the material discharging pipe 5 is driven to move along the track frame 4 by the material leveling rocker arm 7, such as Figure 7 and Figure 8 As shown, the adjusting rod 10 will first abut against the contact plate 16 in the contact member 15, and drive the contact plate 16 and the force storage plate 12 to move correspondingly along the inclined rod 11. Since the inclined plate 11 is not parallel to the track frame 4, the adjusting rod 10 will be separated from the contact plate 16 as the force storage plate 12 moves. At this time, the compressed force storage spring 14 will release its elastic properties, push the force storage plate 12 to move outward along the inclined rod 11, and drive the knocking protrusion 13 to hit the inner wall of the collection box, thereby vibrating the materials stacked in the inner wall, so that the larger part of the gaps in the stacked materials are reorganized, and the gaps in the material stacking are reduced;

[0036] When the discharge pipe 5 retreats and resets along the track frame 4, the adjusting rod 10 will contact the other side of the contact plate 16. In the absence of the limiting effect of the abutment plate 17, the contact plate 16 will rotate until the adjusting rod 10 is separated from the contact plate 16. After separation, the contact plate 16 is again fitted with the abutment plate 17 through the magnetic block, so as to facilitate the next round of adjustment rod 10 and contact plate 16 to abut against each other and drive the force storage plate 12 to move.

[0037] It should be noted that in order to facilitate the smooth separation between the adjusting rod 10 and the contact plate 16, the outer end of the adjusting rod 10 adopts a hemispherical structure. At the same time, in order to prevent the knocking protrusion 13 from causing damage to the inner wall of the aggregate box, the outer end of the knocking protrusion 13 is designed to be made of rubber material.

[0038] For further information, see Figure 2 - Figure 4 The rotating part 3 includes a rotating motor 18 fixed on the bracket 2, a rotating gear 19 is fixed to the output end of the rotating motor 18, and a gear ring 20 meshing with the rotating gear 19 is fixed on the outer wall of the feeding pipe.

[0039] In this solution, when discharging, the rotating motor 18 drives the rotating gear 19 to rotate, and the rotating gear 19 rotates along the gear ring 20, thereby driving the corresponding rotation of the bracket 2 on the rotating tube 1, and cooperating with the discharge tube 5 to perform corresponding rotation discharge.

[0040] For further information, see Figure 4 and Figure 7 - Fig. 9 The material leveling rocker arm 7 includes a driving motor 21 fixed at the bottom of the bracket 2, a connecting rod 22 is fixed to the output end of the driving motor 21 through a coupling, a rocker wheel 23 is fixed to the bottom of the connecting rod 22, a rocker lever 24 is rotatably mounted on the outer end of the rocker wheel 23, and the rocker lever 24 is rotatably connected to the outer wall of the discharge pipe 5 through a rotating shaft.

[0041] The principle of the material leveling rocker arm 7 driving the discharging pipe 5 to move along the track frame 4 is as follows: first, by driving the motor 21 to rotate, the connecting rod 22 and the rocker arm wheel 23 are driven to rotate accordingly. During the rotation of the rocker arm wheel 23, the rocker arm rod 24 is driven to make a corresponding connecting rod movement, so that the discharging pipe 5 moves in the track frame 4 from one end to the other end. Figure 7 - Fig. 9 As shown, the material can be evenly discharged into the collecting box during discharge to avoid the phenomenon of material piling.

[0042] In this solution, the operation of reducing the material accumulation gap and avoiding the occurrence of material pile-up includes the following steps:

[0043] In the first step, the material is transferred to the discharge pipe through the conveying mechanism, and the material enters the spring tube 6 along the discharge pipe and is discharged along the discharge pipe 5;

[0044] In the second step, the bracket 2 is driven to rotate by the rotating part 3, so that the track frame 4 and the discharge pipe 5 rotate in the collection box accordingly;

[0045] In the third step, the material leveling rocker arm 7 is operated to drive the discharge pipe 5 to move along the track frame 4, and the bracket 2 is rotated to achieve uniform material discharge in the collecting box, effectively avoiding the material accumulation caused by the fixed-point discharge of the discharge pipe;

[0046] In the fourth step, each time the discharge pipe 5 moves along the track frame 4, it will drive the force storage plate 12 to move and store force, and finally drive the knocking protrusion 13 to knock against the inner wall of the aggregate box through the force storage spring 14, so that the materials accumulated in the aggregate box vibrate, and some materials with large gaps are reorganized to reduce the gaps between the materials.

[0047] In this solution, the material is discharged according to the above steps. After the material finally reaches the specified scale line, it can ensure that the top material is in a flat state and the gap between the materials is not too large, so that the amount of collected material is more accurate.

[0048] Example 2: Please refer to Figure 5 and Figure 6 This embodiment further explains the first embodiment, and the difference lies in that a flattening portion 28 is disclosed. When the bracket 2 rotates, the flattening portion 28 can flatten the upper layer of material that is about to reach the specified scale line, making the top material flatter, further improving the accuracy of material collection.

[0049] Specifically, a connecting column 25 is fixed at the bottom of the bracket 2, and the connecting column 25 is sleeved on the outside of the connecting rod 22. A connecting frame 26 is fixed at the bottom of the connecting column 25, and two connecting pipes 27 are fixed at the bottom of the connecting frame 26. A flattening portion 28 is fixed at the bottom of the connecting pipe 27.

[0050] The flattening part 28 includes a flattening frame 29 fixed to the bottom of the connecting tube 27, connecting beads 30 are evenly distributed in the two flattening frames 29, a flattening brush is fixed to the bottom of the connecting beads 30, an elastic rope 31 fixed to the end plate of the flattening frame 29 is fixed on the connecting column 25 away from the connecting tube 27, and connecting ropes 32 are fixed between other connecting beads 30. Two connecting blocks 33 are fixed on the connecting frame 26. The connecting rope 32 slides through the flattening frame 29 and the connecting tube 27, and slides through the connecting block 33. A toggle member 34 for driving the connecting rope 32 to twitch is fixed on the connecting rod 22;

[0051] It should be noted that the connecting bead 30 is connected to the end plate of the flattening frame 29 by an elastic rope 31, so that when the connecting rope 32 is pulled, it can drive the connecting bead 30 and the flattening brush to pull in a corresponding taut state.

[0052] The toggle member 34 includes an adjustment disk 35 fixed on the outside of the connecting rod 22, and toggle blocks 36 are fixed at equal angles on the outside of the adjustment disk 35. A docking block 37 is fixed on the outside of the connecting rope 32 located between the two connecting blocks 33, and a return spring 38 is sleeved on the outside of the connecting rope 32 for pushing the docking block 37 to return to its original position.

[0053] In this solution, in order to ensure that the material on the top can remain flat after the material quantity reaches the standard, the material is flattened by the designed flattening part 28 to avoid material accumulation. At the same time, when the material leveling rocker arm 7 is driven, it will drive the connecting rod 22 and the adjusting disk 35 to rotate accordingly, so that the toggle block 36 rotates, and drives the corresponding pulling connecting rope 32 of the docking block 37 to twitch, so that the connecting beads 30 on the connecting rope 32 and the flattening brush twitch accordingly, which is more conducive to the flattening operation of the material, making the material on the top more flat, avoiding the occurrence of bulges, and making the material quantity more accurate.
