When the transverse driving component 3 is in operation, it can drive the two pushing components 4 to operate simultaneously, so that the upper extrusion blocks 42 on the two pushing components 4 move away from each other. When the two upper extrusion blocks 42 move away from each other, they drive the two partitions 51 at the first and last positions to move away from each other. The two partitions 51 pull the partitions 51 of other variable-distance storage baffles 5 to move through the tension springs 9, and the spacing between each partition 51 is consistent, thereby adjusting the spacing between adjacent partitions 51.

[0034] The front and rear sides of the hanger 2 are fixedly connected to two fixed plates 21, wherein a drive motor 31, a transverse double-ended screw rod 32, and a front guide rod 33 are arranged between the two fixed plates 21, and a rear guide rod 34 is fixedly connected between the other two fixed plates 21. The drive motor 31 is fixed to the side of the corresponding fixed plate 21, and both ends of the transverse double-ended screw rod 32 are rotatably connected to the corresponding fixed plate 21, and both ends of the front guide rod 33 are fixedly connected to the corresponding fixed plate 21. The output end of the drive motor 31 passes through the corresponding fixed plate 21 and is fixedly connected to one end of the transverse double-ended screw rod 32, and the outer surface of the transverse double-ended screw rod 32 is provided with threads of opposite rotation directions at both ends.

[0035] The two ends of the top of the partition plate 51 extend to both sides of the hanger 2 respectively to form extension ends. A second screw rod 52 is threadedly connected to the extension ends of the partition plate 51. The variable pitch material storage baffle 5 further includes two movable blocks 53. The movable blocks 53 are located below the extension ends of the partition plate 51, and the partition plate 51 is detachably connected to the movable blocks 53. Threaded holes adapted to the second screw rod 52 are formed in the movable blocks 53. A docking block 511 is fixedly connected to the bottom of the extension end of the partition plate 51. The bottom surface of the docking block 511 is an arc surface. A docking port matching the docking block 511 is formed in the movable block 53. A T-shaped block 531 is fixedly connected to the side surface of the movable block 53 close to the partition plate 51. Horizontal T-shaped grooves 22 are formed in the front and rear side surfaces of the hanger 2. The horizontal T-shaped grooves 22 are adapted to the T-shaped block 531. The T-shaped block 531 can be slidably connected to the inside of the horizontal T-shaped groove 22. A horizontally arranged lower substrate 54 is fixedly connected to the side surface of the partition plate 51. The lower substrate 54 is in sliding contact with the top of the hanger 2 to prevent abrasive leakage. A feeding port for feeding materials is formed in the lower substrate 54. An upper moving plate 55 is slidably connected to the top of the lower substrate 54. Two guiding column bodies 56 are symmetrically and fixedly connected to the side surface of the upper moving plate 55 close to the partition plate 51. The guiding column bodies 56 movably penetrate through the partition plate 51. A spring 57 is sleeved on the guiding column bodies 56. The two ends of the spring 57 are fixedly connected to the upper moving plate 55 and the partition plate 51 respectively. A sealing assembly 6 for sealing the feeding port is arranged on the top of the lower substrate 54. The upper moving plate 55 of the variable pitch material storage baffle 5 abuts against the partition plate 51 of the adjacent variable pitch material storage baffle 5 under the action of the spring 57.

[0036] Further, two cylindrical notches are symmetrically formed in the side surface of the upper moving plate 55 away from the partition plate 51. The cylindrical notches of the upper moving plate 55 are used for the guiding column bodies 56 of the adjacent upper moving plate 55 to pass through. The cross-section of the upper moving plate 55 is in a "凵" shape. The front and rear inner side surfaces of the upper moving plate 55 are in sliding contact with the outer side wall of the hanger 2 to prevent abrasive leakage.

[0037] The pushing assembly 4 also includes a transverse sealing plate 41 and two connecting blocks 45. The two upper extrusion blocks 42 are respectively fixed on the front and rear sides of the transverse sealing plate 41. The transverse sealing plate 41 is in sliding contact with the top of the hanger 2. The transverse sealing plate 41 is used to seal the top sides of the hanger 2. The upper extrusion block 42 is fixedly connected to the transverse sealing plate 41 through the connecting block 45. A plurality of first screws 44 are threadedly connected to the upper extrusion block 42. A lower extrusion block 43 is arranged below the upper extrusion block 42. The lower extrusion block 43 is provided with a threaded hole adapted to the first screw 44. The bottom of the upper extrusion block 42 Two semicircular holes are provided on the top of the lower extrusion block 43, and two semicircular holes are provided on the top of the lower extrusion block 43. The semicircular holes of the lower extrusion block 43 can become a complete circular hole when combined with the semicircular holes of the upper extrusion block 42. The inner side of one of the semicircular holes of the upper extrusion block 42 and the lower extrusion block 43 is provided with a thread adapted to the transverse double-headed screw rod 32. The upper extrusion block 42 and the lower extrusion block 43 are detachably connected by a first screw rod 44. The connection state of the upper extrusion block 42 and the lower extrusion block 43 is threadedly connected to the transverse double-headed screw rod 32, and the transverse double-headed screw rod 32 passes through the upper extrusion block 42 and the lower extrusion block 43.

[0038] Furthermore, the transverse sealing plates 41 are located outside the partitions 51 , and the two transverse sealing plates 41 are in contact with the first and last partitions 51 respectively, so as to prevent the abrasive from leaking out from the gaps between the transverse sealing plates 41 and the partitions 51 .

[0039] When the spacing between the partitions 51 needs to be adjusted, the drive motor 31 is started, and the output end of the drive motor 31 drives the transverse double-headed screw 32 to rotate, so that the upper extrusion blocks 42 on the two transverse sealing plates 41 move away from each other. Because the upper extrusion blocks 42 on the two pushing components 4 are respectively in contact with the first and last partitions 51, the two transverse sealing plates 41 move away from each other, and because there are tension springs 9 between the two adjacent partitions 51, the two partitions 51 pull the partitions of other variable-distance storage baffles 5 through the tension springs 9. 51 moves, and the forces on each tension spring 9 are the same, and the stretching amount is consistent, so that the spacing between each partition 51 is consistent. The closer the partition 51 is to the upper extrusion block 42, the greater the movement of the partition 51. During the movement of the partition 51 of the variable-pitch material storage baffle 5, the upper movable plate 55 of the variable-pitch material storage baffle 5 is always in contact with the partition 51 of the adjacent variable-pitch material storage baffle 5 under the action of the spring 57, thereby ensuring the sealing between the two variable-pitch material storage baffles 5 and avoiding abrasive leakage. When the spacing between each partition 51 reaches the predetermined spacing, the operation of the transverse drive assembly 3 is stopped.

[0040] Both ends of the tension spring 9 are fixedly connected with patches 10, and the two patches 10 are detachably connected to two adjacent movable blocks 53. Specifically, the patch 10 is rotatably connected with a bolt on the side away from the tension spring 9, and a threaded hole 532 for adapting the bolt is provided on the movable block 53. When it is necessary to install the tension spring 9 between two adjacent variable-distance storage baffles 5, the two bolts of the patch 10 are threadedly connected to the threaded holes 532 of the two adjacent movable blocks 53.

[0041] Two additional components 8 are symmetrically arranged on the front and rear sides of the hanger 2, and the additional component 8 includes a stopper 81. Two vertical slide grooves 23 are symmetrically opened on the front and rear sides of the hanger 2. The vertical slide grooves 23 are vertically arranged and connected with the horizontal T-slot 22. The stopper 81 is arranged at the connection between the vertical slide groove 23 and the horizontal T-slot 22. A connecting rod 82 is fixedly connected to the side of the stopper 81. The additional component 8 also includes two connecting rods 83 fixed to the outer side of the hanger 2. A fixed shaft 84 is fixedly connected between the two connecting rods 83. The fixed shaft 84 passes through the connecting rod 82. The connecting rod 82 is rotatably connected to the fixed shaft 84. A torsion spring 85 is installed between the connecting rod 82 and the fixed shaft 84. The size of the connection between the vertical slide groove 23 and the horizontal T-slot 22 has been enlarged for the rotational passage of the stopper 81.

[0042] When it is necessary to add multiple smaller workpieces to a material storage trough, it is necessary to add the number of variable-pitch material storage stops 5 to the material storage trough, rotate the first screw 44 so that the first screw 44 disengages from the lower extrusion block 43, and then separates the upper extrusion block 42 from the lower extrusion block 43, remove the pushing assembly 4 from the horizontal driving assembly 3, embed the T-block 531 of the new movable block 53 into the vertical slide groove 23, rotate the connecting rod 82, and the connecting rod 82 drives the stopper 81 to disengage from the vertical slide groove 23 and the horizontal T-slot 22, so that the stopper 81 cannot hinder the movable block 53, and then let the T-block 531 move vertically along the vertical slide groove 23 into the horizontal T-slot 22, release the connecting rod 82, and the connecting rod 82 rotates under the action of the torsion spring 85, and the connecting rod 82 drives the stopper 531 to move vertically along the vertical slide groove 23 into the horizontal T-slot 22. Block 81 rotates to its initial position to prevent the new movable block 53 from re-entering the vertical slide groove 23, a tension spring 9 is installed between the new movable block 53 and another adjacent movable block 53, a new partition 51 is installed above the new movable block 53, and a new second screw 52 is used to connect the new partition 51 to the new movable block 53, the docking block 511 of the new partition 51 is embedded in the docking interface of the new movable block 53, the front guide rod 33 and the rear guide rod 34 are on the inner side of this combined structure to realize the guiding function, the new variable-pitch storage stopper 5 is updated to become the first variable-pitch storage stopper 5, and then the disassembled pushing assembly 4 is reinstalled on the horizontal driving assembly 3, and it is ensured that the upper extrusion blocks 42 on the two pushing assemblies 4 are respectively abutted against the two partitions 51 in the first and last positions.
