Description

Technical Field

[0002] Flange, also known as flange flange or flange, is one of the essential parts in mechanical equipment. Flange is a part that connects shafts to each other and is used to connect pipe ends; it is also used as a flange on the inlet and outlet of equipment to connect two devices.

[0003] After the production and processing of the flanges are completed, they will be stacked together for subsequent transportation. After the flanges are stacked, a layer of packaging paper needs to be placed at both ends of the packaging paper for protection. The flange packaging paper is generally stacked together, and the paper needs to be placed one by one on the conveyor line manually, and then the conveyor line will transfer the paper to the stacking station and wait for stacking.

[0004] Since the amount of flange packaging paper is large, if manual feeding is used, the efficiency is low and manual repetition of an action will easily cause fatigue. Therefore, the best way is to use a machine to feed. Automatic feeding by machine requires limiting the packaging paper to prevent the stacked packaging paper from collapsing or deflecting when the machine grabs it, which will affect the machine's grasping. There are many types of flanges, and the diameters are also different. Flanges of different diameters require packaging paper of different diameters, but the currently used limiting mechanism cannot meet the requirements of limiting packaging paper of different diameters. It has certain limitations and cannot meet the actual production needs. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, a preferred embodiment of the utility model proposes a silo-adjustable feeding device, which is mainly composed of two parts, including a conveying mechanism 4 and a feeding mechanism. The feeding mechanism is used to store the stacked packaging paper shells and transfer the packaging paper shells one by one to the conveying mechanism 4, and then the conveying mechanism 4 transports the packaging paper shells to the designated position.

[0027] like Figure 2 , Figure 3 As shown, the feeding mechanism is mainly composed of components such as a support frame 1, a silo 2, a lifting assembly 5, an adjustment assembly 6 and a transplanting assembly 3, wherein the silo 2 is installed on the support frame 1, and the silo 2 is composed of a bearing plate 21 and four limit plates 22. Four slide rails distributed in a "cross" shape are arranged on the support frame 1, and the lower end of the limit plate 22 is slidably connected to the slide rail through a slider. The bearing plate 21 is used to carry the packaging paper shell, and a accommodating space for accommodating the packaging paper shell is formed between the four limit plates 22. The bearing plate 21 is square, and avoidance holes are opened on the four sides of the bearing plate 21. The avoidance holes are formed by extending from the edge of the bearing plate 21 toward the center direction of the bearing plate 21, so that when the four limit plates 22 move toward the center direction of the bearing plate 21, they will pass through the avoidance holes and will not interfere with the movement of the limit plates 22.

[0028] Correspondingly, four sliding holes corresponding to the positions of the limiting plate 22 are also opened on the support frame 1, and a connecting plate 7 is arranged on the lower side of the limiting plate 22. The connecting plate 7 is installed on the slider, and the lower end of the connecting plate 7 passes through the sliding hole and extends downward.

[0029] like Figure 2 As shown, four proximity switches 10 are further arranged below the carrying plate 21 . The four proximity switches 10 correspond to the positions of the four limit plates 22 , respectively. The proximity switches 10 are used to detect the moving distance of the limit plates 22 .

[0030] refer to Figure 3 The adjustment assembly 6 is also installed at the bottom of the support frame 1. In this embodiment, there are two adjustment assemblies 6, and each adjustment assembly 6 controls the movement of two limit plates 22;

[0031] refer to Figure 3 , Figure 4The adjusting assembly 6 is composed of an adjusting motor 62, a motor fixing bracket 61, a mounting bracket 64, a synchronous wheel 65, a transmission wheel and a synchronous belt 63, wherein the motor fixing bracket 61 is installed and fixed on one side of the bottom of the support frame 1, and a strip hole is opened on the side of the support frame 1 opposite to the motor fixing bracket 61, and the lower end of the mounting bracket 64 passes through the strip hole and extends downward, and an adjusting bolt 8 is horizontally arranged on the mounting bracket 64, the adjusting bolt 8 is threadedly connected to the support frame 1, and one end thereof is inserted into the strip hole and fixedly connected to the mounting bracket 64, and the synchronous wheel 65 is rotatably connected to the bottom of the mounting bracket 64, the adjusting motor 62 is installed at the bottom of the motor fixing bracket 61, the transmission wheel is connected to the output end of the adjusting motor 62, and the two ends of the synchronous belt 63 are respectively connected to the transmission wheel and the synchronous wheel 65, and the connecting plates 7 on the lower sides of the two limit plates 22 are respectively fixedly connected to the two parallel belts of the synchronous belt 63, so that the adjusting motor 62 can drive the two limit plates 22 to move toward or away from the center direction of the bearing plate 21 through the synchronous belt 63.

[0032] When the tension of the synchronous belt 63 is insufficient, the synchronous belt 63 can be tightened by rotating the adjusting bolt 8 to drive the mounting bracket 64 to move along the strip hole on the support frame 1 .

[0033] refer to Figure 3 The synchronous belts 63 in the two adjustment components 6 are cross-distributed. The four limit plates 22 can be controlled to move toward or away from the center direction of the carrier plate 21 through the two adjustment components 6. In this way, the cross-sectional area of ​​the accommodating space can be adjusted according to the different diameters of the packaging paper shells, so as to limit the packaging paper shells of different diameters and prevent the position of the packaging paper shells from being skewed.

[0034] refer to Figure 2 A cushion block 23 with a certain elasticity is arranged on the inner side of each limiting plate 22 to prevent the limiting plate 22 from rigidly contacting the packaging paper shell and damaging the packaging paper shell.

[0035] like Figure 3 As shown, the lifting assembly 5 is installed and fixed at the bottom of the support frame 1. The lifting assembly 5 is composed of a cylinder fixing frame 51 and a lifting cylinder 52. The cylinder fixing frame 51 is installed and fixed at the bottom of the support frame 1, and the lifting cylinder 52 is vertically fixed at the bottom of the cylinder fixing frame 51. The output end of the lifting cylinder 52 passes through the support frame 1 upward and is fixedly connected to the bottom center of the bearing plate 21. The bearing plate 21 is lifted upward by the lifting cylinder 52.

[0036] When the packaging paper shell is placed on the carrying plate 21 , the center of gravity of the carrying plate 21 may be unstable. Therefore, the avoidance hole on the carrying plate 21 cooperates with the limiting plate 22 to prevent the carrying plate 21 from deflecting to one side.

[0037] Every time the transplanting component 3 transfers a packaging paper shell, the lifting component 5 will lift the supporting plate 21 upward to a position of the height of the packaging paper shell. In order to accurately grasp the height change of the packaging paper shell, a through-shooting sensor 9 is arranged on the top of two relatively distributed limit plates 22. When the through-shooting sensor 9 detects that the packaging paper shell of the uppermost layer of the packaging paper shell has reached the specified position, the lifting component 5 will stop working.

[0038] like Figure 5 As shown, the transplanting assembly 3 is composed of components such as a bracket, a moving module 33, a lifting cylinder 34, an adjusting plate 35, a suction cup fixing bracket 36 and a suction cup 37, wherein the bracket is composed of a mounting plate 32 and two columns 31, the two columns 31 are vertically fixed on both sides of the support frame 1, and the two ends of the mounting plate 32 are fixedly connected to the top ends of the two columns 31, respectively. The mounting plate 32 is vertically arranged, and the moving module 33 is horizontally fixed at the bottom of the mounting plate 32. The moving direction of the moving module 33 is consistent with the conveying direction of the conveying mechanism 4. The lifting cylinder 34 is vertically installed on the moving module 33, and the lifting and horizontal movement is controlled by the moving module 33.

[0039] refer to Figure 6 The adjustment plate 35 is fixedly connected to the output end of the lifting cylinder 34. The adjustment plate 35 has a plurality of linearly distributed adjustment holes 351. Two suction cup fixing brackets 36 are provided. The two suction cup fixing brackets 36 are respectively installed at the two ends of the adjustment plate 35 by bolts. The position between the two suction cup fixing brackets 36 can be adjusted through the adjustment holes 351. Strip holes are opened near the two ends of each suction cup fixing bracket 36. At least one suction cup 37 is arranged in each strip hole, that is, there are at least four suction cups 37 in total, and the spacing between the suction cups 37 can be adjusted through the strip holes.

[0040] During operation, the lifting cylinder 34 controls the suction cup 37 to move downward, and the suction cup 37 will suck the packaging paper shell in the silo 2, and control the movement through the moving module 33 to transfer the packaging paper shell to the conveying mechanism 4, and then the conveying mechanism 4 will transport the packaging paper shell to the designated position.

[0041] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
