DETAILED DESCRIPTION

[0022] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Reference Figures 1 to 4 , an embodiment provided by the utility model:

[0024] An automatic feeding device for composite processing of profiles, comprising a transport mechanism, a lifting mechanism arranged at the end of the transport mechanism, and a feeding mechanism arranged above the lifting mechanism, characterized in that:

[0025] The transport mechanism includes a horizontally arranged conveyor belt 1, and limit plates 2 arranged on both sides of the conveyor belt 1, the limit plates 2 are symmetrically arranged with respect to the conveyor belt 1, and are inclined toward the end of the conveyor belt 1;

[0026] The lifting mechanism includes a rotatably arranged sprocket and a chain belt 3 connected to the sprocket. The chain belt 3 is arranged vertically. A supporting plate 4 is arranged at intervals on the outer side of the chain belt 3. The supporting plate 4 is flush with the surface of the conveyor belt 1.

[0027] The feeding mechanism includes a horizontally arranged base plate 5, a conveying platform 6 slidably connected to the base plate 5, a clamp 7 corresponding to the position of the supporting plate 4, and a positioning block 8 arranged opposite to the clamp 7. The clamp 7 is flush with the surface of the conveying platform 6 and is connected to a clamping cylinder.

[0028] The automatic feeding device is used for composite processing of profiles, including a transport mechanism, a lifting mechanism, and a feeding mechanism. The transport mechanism realizes the material sorting function, the lifting mechanism realizes the intermittent feeding function, and the feeding mechanism provides an independent delivery function. The transport mechanism is installed horizontally, with the end where the operator feeds the material as the starting end and the other end as the end. The lifting mechanism is installed vertically and is located at the end of the transport mechanism. The profile enters from the bottom of the lifting mechanism and is sent out from the top. The feeding mechanism is installed horizontally and is located above the lifting mechanism. The end that connects to the lifting mechanism is the starting end and the other end is the end.

[0029] The transport mechanism includes a conveyor belt 1 and a limit plate 2. The conveyor belt 1 is arranged horizontally, and the profile enters from the beginning of the conveyor belt 1 and is sent out from the end. The conveyor belt 1 can be arranged in two rows in parallel, and the two rows of conveyor belts 1 are supported at both ends of the profile. The position between the two rows of conveyor belts 1 is used to install the lifting mechanism, which saves installation space and provides sufficient avoidance space for the support plate 4 of the lifting mechanism to avoid interference and collision between the support plate 4 and the conveyor belt 1. The conveyor belt 1 can be internally connected to a transmission wheel that meshes with the conveyor belt 1, and the transmission wheel is connected to a transmission shaft, and the transmission shaft is connected to a transmission motor. Under the drive of the transmission motor, the transmission shaft and the transmission wheel rotate, and the conveyor belt 1 rotates through the meshing transmission to provide a profile transportation function.

[0030] The limit plates 2 are installed on both sides of the conveyor belt 1 and are arranged in the same direction as the conveyor belt 1. The two limit plates 2 are symmetrically arranged about the conveyor belt 1 and are inclined toward the end of the conveyor belt 1. The limit plates 2 may have one end relative to the starting end of the conveyor belt 1 as the feeding end and the other end as the gathering end. The distance between the feeding ends of the two limit plates 2 is greater than the length of the profile, and the distance between the gathering ends of the two limit plates 2 is equal to the length of the profile. After the profile is placed at the starting end of the conveyor belt 1, the limit plates 2 limit the ends of the profile, and at the same time, the distance between the two limit plates 2 gradually decreases, limiting the alignment of the limit plates 2 with the middle of the conveyor belt 1, providing a profile guiding function.

[0031] The lifting mechanism includes a sprocket, a chain belt 3, and a supporting plate 4. The sprocket is rotatably arranged and located at the end of the conveyor belt 1. The chain belt 3 is vertically arranged. The sprocket is connected to the chain belt 3 in a transmission manner. The outer side of the sprocket is meshed with the inner side of the chain belt 3 for transmission. The chain belt 3 has the end that is connected to the conveyor belt 1 as the bottom end and the other end as the top end. The top end of the chain belt 3 is connected to the feeding mechanism. The sprocket can be rotatably connected to a sprocket shaft, which is horizontally arranged and laterally aligned with the conveyor belt 1. The sprocket shaft is connected to a sprocket motor. Under the drive of the sprocket motor, the sprocket shaft and the sprocket rotate. Through the meshing transmission, the chain belt 3 is rotated to provide a profile lifting function.

[0032] There are several supporting plates 4, which are evenly arranged and spaced around the outer side of the chain belt 3. The supporting plate 4 is L-shaped and faces the end of the conveyor belt 1. It can include a vertical supporting plate and a supporting plate flush with the surface of the conveyor belt 1. After the profile is transported to the end of the conveyor belt 1, the supporting plate blocks the profile so that it stays on the surface of the supporting plate and is lifted upward as the chain belt 3 rotates. In addition, multiple profiles are guided by the limit plate 2 and arranged at the end of the conveyor belt 1. By controlling the movement stroke of the sprocket and the chain belt 3, the supporting plate 4 can be intermittently lifted and lowered, and multiple profiles are lifted one by one to the feeding mechanism.

[0033] The feeding mechanism includes a bottom plate 5, a conveying platform 6, a clamping hand 7, a positioning block 8, and a clamping cylinder. The bottom plate 5 is horizontally arranged and is perpendicular to the conveyor belt 1 in a non-planar manner to ensure that the placement direction of the profile when feeding is the same as the conveying direction when loading. The bottom plate 5 has one end that is connected to the top of the chain belt 3 as the starting end and the other end as the end. After the profile is conveyed by the transportation mechanism, the lifting mechanism, and the feeding mechanism, it is sent from the end of the bottom plate 5 to the next process. The conveying platform 6 is slidably connected to the top of the bottom plate 5 and slides along the direction of the conveying platform 6. The bottom plate 5 and the conveying platform 6 can be respectively provided with a transmission guide rail and a transmission guide wheel connected by a transmission motor. The transmission guide wheel is connected to a transmission motor. Under the drive of the transmission motor, the transmission guide wheel moves along the direction of the transmission guide rail, thereby controlling the movement of the conveying platform 6. The conveying platform 6 is equipped with a positioning block 8, which can be integrated with the conveying platform 6. The positioning block 8 and the clamping hand 7 are arranged opposite to each other to provide a positioning reference for clamping. The gripper 7 is telescopic relative to the conveyor 6, and the telescopic direction is perpendicular to the bottom plate 5. One end of the gripper 7 is connected to the clamping cylinder, and the other end corresponds to the position of the support plate 4. It can be located outside the support plate 4, corresponding to the two ends of the profile, and the surfaces of the two are flush. Driven by the clamping cylinder, the gripper 7 moves toward the chain belt 3. As the clamping cylinder retreats, the profile on the support plate 4 enters the gripper 7 and moves toward the positioning block 8, so that the profile is fixed on the conveyor 6. The conveyor 6 moves along the bottom plate 5 to transport the profile to the next process.

[0034] The utility model is used for composite processing of profiles. First, multiple profiles are placed on the surface of the conveyor belt 1. Under the guidance of the limit plate 2, the two ends of the profiles are transported to the end of the conveyor belt 1 in turn until they are docked with the support plate 4, and the support plate supports the profiles. Then, through the transmission action of the sprocket and the chain belt 3, the support plate 4 moves upward intermittently and lifts the profiles one by one until they are flush with the clamp 7. Finally, driven by the clamping cylinder, the profile located on the support plate 4 enters the clamp 7 and moves toward the positioning block 8, so that the profile is fixed on the conveyor table 6. The conveyor table 6 moves along the bottom plate 5 to transport the profile to the next process. The utility model realizes functions such as material sorting, intermittent feeding, and independent delivery. The operator only needs to feed the material at the beginning of the transmission belt to realize a fully automated loading process and effectively improve production efficiency.
