DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1-7 , a technical solution provided by an embodiment of the present invention: the material conveying mechanism includes a body 1, a linkage assembly, a first transmission assembly and a second transmission assembly, a rotating rod 17 is rotatably connected in the body 1, a connecting block 3 is vertically slidably connected to the body 1, a first abutting block 6 is provided at the bottom of the connecting block 3 through an elastic unit, and a clamping plate 11 for clamping the material basket is provided on both sides of the first abutting block 6 through a connecting unit, the linkage assembly is driven by the first abutting block 6 during the downward movement so that the two clamping plates 11 are close to the material basket, and the two clamping plates 11 are abutted and matched with the two sides of the plastic basket in a one-to-one correspondence, the first transmission assembly is driven by the rotation of the rotating rod 17 so that the two clamping plates 11 move vertically back and forth up and down, and the second transmission assembly is driven by the rotating rod 17 of the rotating rod 17 so that the two clamping plates 11 rotate synchronously, specifically, a cylinder 2 is provided on the top of the body 1, and the output end of the cylinder 2 is fixedly connected to the connecting block 3 The elastic unit includes a telescopic rod 4 and a first spring 5 sleeved on the telescopic rod 4. The telescopic rod 4 is arranged between the connecting block 3 and the first abutment block 6. The two ends of the first spring 5 are fixedly connected to the connecting block 3 and the first abutment block 6 respectively. A driven rod is rotatably connected in the body 1. The driven rod and the rotating rod 17 are symmetrically sleeved with two sprockets. The two sprockets on the driven rod correspond one to one with the two sprockets on the rotating rod 17. Any sprocket is commonly connected to the corresponding sprocket with a chain for transporting a material basket. Specifically, the two connecting units include a first bracket 7, a connecting rod 8 and a movable rod 10. The first bracket 7 is fixedly connected to one side of the first abutment block 6. The connecting rod 8 is horizontally slidably connected to the first bracket 7. A limiting groove 23 is vertically opened on one side of the connecting rod 8. The movable rod 10 is movably connected in the limiting groove 23. The ends of the two movable rods 10 that are close to each other are fixedly connected to the two clamping plates 11 one by one.

[0028] As a preferred technical solution, the linkage assembly includes two second abutment blocks 9 and two fixed blocks 15, the two fixed blocks 15 are arranged in the body 1, the two second abutment blocks 9 are fixedly connected to one side of the two connecting rods 8, the bottom ends of the two second abutment blocks 9 are inclined, and the two fixed blocks 15 are slidably abutted against the two second abutment blocks 9 one by one. Specifically, two grooves 32 are symmetrically opened in the body 1, and the two fixed blocks 15 are fixedly connected in the two grooves 32 respectively. When the first bracket 7 drives the connecting rod 8 to move downward, due to the sliding abutment between the second abutment blocks 9 and the fixed blocks 15, the connecting rod 8 moves toward the bottom during the downward movement. The connecting rod 8 moves downwardly further than the bottom of the basket 11 and the two clamps 11 move toward the basket.

[0029] As a preferred technical solution, the first transmission assembly includes two symmetrically arranged first transmission units, and the two first transmission units include a third abutment block 13, a pushing block 14, a slider 16 and a protrusion 31. The slider 16 is horizontally slidably sleeved on the rotating rod 17 through the protrusion 31. The slider 16 is fixedly connected to the pushing block 14. The bottom end of the third abutment block 13 is inclined. The pushing block 14 slides and abuts with the bottom end of the third abutment block 13. Two second slide grooves 27 are symmetrically and vertically opened in the body 1. The two third abutment blocks 13 are slidably connected with the two second slide grooves 27 in a one-to-one correspondence. The top ends of the two third abutment blocks 13 abut and cooperate with the two movable rods 10 in a one-to-one correspondence. Specifically, two third slide grooves 28 are symmetrically opened in the body 1. The two pushing blocks 14 are slidably connected with the two third slide grooves 28 in a one-to-one correspondence. Two guide grooves are symmetrically opened in the body 1. The two sliders 16 are slidably connected with the two guide grooves in a one-to-one correspondence. The two protrusions 31 are respectively arranged in the inner and outer surfaces of the two sliders 16. The two slide grooves 18 are symmetrically provided on the rotating rod 17, and the two protrusions 31 are slidably connected with the two slide grooves 18 in a one-to-one manner. The two slide grooves include two spiral grooves 18 connected head to tail. When the two clamping plates 11 clamp the material basket, the two clamping plates 11 no longer change in the horizontal direction. Through the rotation of the rotating rod 17, the sliding cooperation between the protrusions 31 and the spiral grooves 18 is achieved. Since the guide groove limits the circumferential rotation of the slider 16, the slider 16 drives the pushing block 14 to slide toward the third abutting block 13. Since the bottom end of the third abutting block 13 is inclined, the pushing block 14 slides and abuts with the third abutting block 13, so that the third abutting block 13 moves up. At this time, the two clamping plates 11 have clamped the material basket, and the third abutting block 13 abuts against the movable rod 10, driving the material basket to move up, which is convenient for subsequent flipping and avoiding movement interference. Preferably, the cross-sectional area of ​​the pushing block 14 is larger than the cross-sectional area of ​​the third abutting block 13, which can keep the movable rod 10 at the highest point for a period of time.

[0030] As a preferred technical solution, the second transmission assembly includes two symmetrically arranged second transmission units, and the two second transmission units each include a gear body 12, an irregular gear 19, two first racks 20, two connecting plates 30, a second bracket 21 and a second rack 22 meshing with the gear body 12, the two first racks 20 are symmetrically arranged between the two connecting plates 30, the irregular gear 19 is sleeved on the rotating rod 17, the irregular gear 19 is meshed with the two first racks 20 in sequence, the second bracket 21 is respectively fixedly connected to the second rack 22 and one of the first racks 20, the two gear bodies 12 are sleeved with the two movable rods 10 one by one, and specifically, a first gear body 1 is provided in the machine body 1. There are four slide grooves 29, and the two first racks 20 are horizontally slidably connected in the fourth slide groove 29. The rotating rod 17 drives the irregular gear 19 to rotate, and the irregular gear 19 meshes with the first rack 20 located below, and drives the second rack 22 to slide horizontally toward the rotating rod 17 through the second bracket 21. At this time, the movable rod 10 is already at the highest point, and the second rack 22 meshes with the gear body 12 on the movable rod 10. The material basket is flipped through the clamping plate 11, and then the movable rod 10 moves down with the third abutment block 13, and the gear body 12 also moves down at the same time. When the irregular gear 19 meshes with the first rack 20 located above, the second rack 22 is prevented from sliding reversely and meshing with the gear body 12.

[0031] As a preferred technical solution, a first slide groove 25 is opened in the first bracket 7, and a fixed rod 24 is horizontally arranged in the first slide groove 25. The connecting rod 8 is slidably sleeved on the fixed rod 24, and a second spring 26 is sleeved on the fixed rod 24. The two ends of the second spring 26 are respectively fixedly connected to the connecting rod 8 and the side wall of the first slide groove 25. Specifically, the elastic deformation of the second spring 26 can reset the connecting rod 8 to the initial position, loosening the clamping of the material basket, which is convenient for the next operation process.

[0032] As a preferred technical solution, a plurality of anti-sliding blocks 16 are provided on the side where the two clamping plates 11 are close to each other. Specifically, the friction required for clamping can be increased. Preferably, if the two sides of the basket are hollow, the anti-sliding blocks 16 can be inserted into the side through holes of the basket, which can not only remove some impurities but also make the clamping more stable.

[0033] The present invention also provides a spray machine, comprising the above-mentioned material conveying mechanism.

[0034] Working principle: When the bottom of the material basket faces downward, the first abutment block 6 moves downward, the fixed block 15 pushes the second abutment block 9 to slide horizontally, the connecting rod 8 drives the clamping plate 11 to move toward the material basket through the movable rod 10 to clamp the material basket, and at the same time, the rotating rod 17 is rotated, and the sliding block 16 drives the pushing block 14 to slide toward the third abutment block 13 through the sliding cooperation between the protrusion 31 and the spiral groove 18, and the pushing block 14 pushes the third abutment block 13 to move upward. At this time, the two clamping plates 11 have clamped the material basket, and the third abutment block 13 abuts against the movable rod 10, driving the material basket to move upward, and the rotating rod 17 drives the irregular gear 19 to rotate, and the irregular The gear 19 meshes with the first rack 20 located below, and drives the second rack 22 to slide horizontally toward the rotating rod 17 through the second bracket 21. At this time, the movable rod 10 is already at the highest point, and the second rack 22 meshes with the gear body 12 on the movable rod 10. The material basket is flipped through the clamping plate 11, and then the movable rod 10 moves down with the third abutment block 13, and the bottom of the material basket faces upward, which is convenient for subsequent cleaning, improves work efficiency, and reduces labor costs. If the bottom of the material basket faces upward from the beginning, the first abutment block 6 contacts with the bottom of the basket, and the first abutment block 6 will not continue to move down, and the subsequent flipping operation of the material basket will not be performed.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
