Description

Technical Field

[0001] This utility model relates to the technical field of tie rod processing equipment, and in particular to an automatic feeding device for tie rod drilling devices. Background Technology

[0002] Pull handles are common components in suitcases, primarily assisting users in lifting and pulling the suitcase, thus saving effort. Since users have different heights and arm lengths, the extension length of the pull handle varies. To facilitate user use, several fixing holes are usually drilled on the pull handle for secure mounting. Currently, pull handle drilling is typically done manually by workers placing the pull handle on a workstation and then pressing holes using a drilling device. This method has two drawbacks: first, it is inefficient and difficult to meet the demands of mass production; second, if a conveyor belt is used to feed the pull handles directly, the spacing between adjacent pull handles is too small, making it difficult to clamp and place them at the workstation. Therefore, a new type of pull handle feeding device is needed. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an automated feeding device for a tie rod punching device that is highly automated and can ensure stable feeding of tie rods.

[0004] The technical solution of this utility model is as follows: An automatic feeding device for a tie rod punching device includes a device base, a storage frame connected to the device base, a first feeding device connected to the device base, a second feeding device connected to the device base, and a controller. The first feeding device includes a fixed plate fixedly connected to the first feeding device, a first conveyor belt connected to the fixed plate, a plurality of fixed blocks fixedly connected to the first conveyor belt, and a first drive motor for driving the first conveyor belt to move. The fixed blocks are evenly distributed on the first conveyor belt. There is a certain gap between the bottom of the fixed plate and the bottom of the storage frame. The gap between the fixed plate and the bottom of the storage frame can accommodate the fixed blocks to pass through. The second feeding device includes a fixed frame connected to the device base, a second conveyor belt movably connected to the fixed frame, and a second drive motor for driving the second conveyor belt to move. One end of the first conveyor belt and one end of the second conveyor belt are positioned correspondingly. The fixed plate is at a certain angle to the horizontal plane. The movement direction of the tie rod on the second conveyor belt is horizontal. The controller is electrically connected to the first drive motor and the second drive motor respectively. Using the above technical solution, firstly, the pull rods to be processed are placed in batches in the storage box. Then, the controller controls the first drive motor to drive the first conveyor belt. Since there are several fixed blocks on the first conveyor belt, as the fixed blocks move with the first conveyor belt, they will lock the pull rods on the storage box near the fixed plate between two adjacent fixed blocks. Then, the pull rods move with the fixed blocks to the corresponding positions of the first and second conveyor belts. The pull rods are transferred from the first conveyor belt to the second conveyor belt. Then, the second drive motor drives the second conveyor belt to move, so that the pull rods move with the second conveyor belt towards the workstation to facilitate the subsequent pull rod drilling work. Compared with the traditional method of manually loading pull rods, this greatly improves the degree of automation and increases production efficiency.

[0005] A further feature of this invention is that the fixing block is provided with anti-slip texture, which is evenly distributed on the outer surface of the fixing block.

[0006] By adopting the above technical solution, the anti-slip texture on the fixed block can greatly improve the stability of the relative position between the pull rod and the fixed block during the movement of the pull rod with the fixed block, thereby improving the accuracy of the pull rod feeding and reducing the equipment failure rate.

[0007] A further feature of this invention is that the width of the storage frame is adapted to the length of the pull rod to be processed, and a connecting plate is provided at the bottom of the storage frame. The connecting plate is at a certain angle to the horizontal plane, and the height of the end of the connecting plate near the fixed plate is lower than the height of the end of the connecting plate away from the fixed plate.

[0008] By adopting the above technical solution, since the width of the storage box is matched with the length of the pull rod to be processed, the feeding position of the pull rod can be kept stable, thus ensuring accurate drilling position when drilling holes in the pull rod later. Since the height of the end of the connecting plate near the fixed plate is lower than the end of the connecting plate away from the fixed plate, the pull rods stacked on the connecting plate will automatically slide in the direction of the connecting rod, thereby further improving the automation level of the device and improving the feeding efficiency of the pull rod.

[0009] A further feature of this invention is that the fixed frame is provided with a sliding base slidably connected to the fixed frame, several support blocks fixedly connected to the sliding base, and a hydraulic cylinder for driving the sliding base to move vertically. The support blocks are L-shaped, and their movement trajectory does not coincide with the movement trajectory of the second conveyor belt. The hydraulic cylinder is electrically connected to the controller. By adopting the above technical solution, since the fixed frame is provided with a sliding base slidably connected to the fixed frame, several support blocks fixedly connected to the sliding base, and a hydraulic cylinder for driving the sliding base to move vertically, when the pull rod moves with the second conveyor belt to the position of the support block, the L-shaped support block will prevent the pull rod from continuing its previous movement. Then, the controller controls the hydraulic cylinder to drive the sliding base to move vertically upward, thereby making the height of the pull rod match the height of the workstation to be processed, thus further improving the feeding efficiency and ensuring the accuracy of the feeding position.

Detailed Implementation

[0012] like Figure 1As shown, an automatic feeding device for a rod punching device includes a base 1, a storage frame 2 connected to the base 1, a first feeding device 3 connected to the base 1, a second feeding device 4 connected to the base 1, and a controller 5. The first feeding device 3 includes a fixed plate 6 fixedly connected to the first feeding device 3, a first conveyor belt 7 connected to the fixed plate 6, a plurality of fixed blocks 8 fixedly connected to the first conveyor belt 7, and a first drive motor 9 for driving the first conveyor belt 7 to move. The fixed blocks 8 are evenly distributed on the first conveyor belt 7. The bottom of the fixed plate 6 is connected to the storage frame 2. There is a certain gap at the bottom, and the gap between the fixed plate 6 and the bottom of the storage frame 2 can accommodate the fixed block 8 to pass through. The second feeding device 4 includes a fixed frame 10 connected to the equipment base 1, a second conveyor belt 11 movably connected to the fixed frame 10, and a second drive motor 12 for driving the second conveyor belt 11 to move. One end of the first conveyor belt 7 corresponds to one end of the second conveyor belt 11. The fixed plate 6 is at a certain angle to the horizontal plane. The direction of movement of the pull rod on the second conveyor belt 11 is horizontal. The controller 5 is electrically connected to the first drive motor 9 and the second drive motor 12 respectively.

[0013] First, the pull rods to be processed are placed in batches in the storage box 2. Then, the controller 5 controls the first drive motor 9 to drive the first conveyor belt 7. Since the first conveyor belt 7 is equipped with several fixing blocks 8, as the fixing blocks 8 move with the first conveyor belt 7, they will lock the pull rods on the storage box 2 near the fixing plate 6 between two adjacent fixing blocks 8. Then, the pull rods move with the fixing blocks 8 to the corresponding positions of the first conveyor belt 7 and the second conveyor belt 11, and the pull rods are transferred from the first conveyor belt 7 to the second conveyor belt 11. Then, the second drive motor 12 drives the second conveyor belt 11 to move, so that the pull rods move with the second conveyor belt 11 towards the workstation to facilitate the subsequent pull rod drilling work. Compared with the traditional method of manually loading the pull rods, the automation level is greatly improved and the production efficiency is increased. The fixing blocks 8 are provided with anti-slip textures 13, which are evenly distributed on the outer surface of the fixing blocks 8.

[0014] Because the fixed block 8 has anti-slip texture 13, the stability of the relative position between the pull rod and the fixed block 8 can be greatly improved during the movement of the pull rod with the fixed block 8, thereby improving the accuracy of the pull rod feeding and reducing the equipment failure rate.

[0015] The width of the storage box 2 is adapted to the length of the pull rod to be processed. A connecting plate 14 is provided at the bottom of the storage box 2, and the connecting plate 14 is at a certain angle to the horizontal plane. The height of the end of the connecting plate 14 near the fixed plate 6 is lower than the height of the end of the connecting plate 14 away from the fixed plate 6. Because the width of the storage box 2 is adapted to the length of the pull rod to be processed, the feeding position of the pull rod can be ensured to be stable, thereby ensuring accurate drilling position when drilling holes in the pull rod later. Since the height of the end of the connecting plate 14 near the fixed plate 6 is lower than the height of the end of the connecting plate 14 away from the fixed plate 6, the pull rods stacked on the connecting plate 14 will automatically slide towards the connecting rod, thereby further improving the automation level of the device and increasing the feeding efficiency of the pull rod.

[0016] The fixed frame 10 is provided with a sliding base 15 slidably connected to the fixed frame 10, a plurality of support blocks 16 fixedly connected to the sliding base 15, and a hydraulic cylinder 17 for driving the sliding base 15 to move in the vertical direction. The support blocks 16 are L-shaped, and the movement trajectory of the support blocks 16 does not coincide with the movement trajectory of the second conveyor belt 11. The hydraulic cylinder 17 is electrically connected to the controller 5.

[0017] Since the fixed frame 10 is equipped with a sliding base 15 slidably connected to the fixed frame 10, several support blocks 16 fixedly connected to the sliding base 15, and a hydraulic cylinder 17 for driving the sliding base 15 to move vertically, when the pull rod moves with the second conveyor belt 11 to the position of the support block 16, since the support block 16 is L-shaped, the support block 16 will block the pull rod from continuing its previous movement. Then, the controller 5 controls the hydraulic cylinder 17 to drive the sliding base 15 to move vertically upward, so that the height of the pull rod is matched with the height of the work station to be processed, thereby further improving the feeding efficiency and ensuring the accuracy of the feeding position.
