Description

Technical Field

[0001] The invention relates to the technical field of sheet material feeding, in particular to a counterweight sheet feeding device for a mold frame. Background Art

[0002] In the process of making the mold frame counterweight, it is necessary to press multiple counterweight plates together according to the set number, and then coat the outer periphery with rubber to form a counterweight unit with a certain unit weight, which can be increased or decreased according to the needs of the user. In the process of assembling and crimping the counterweight plates, a certain number of counterweight plates need to be riveted together with the help of a crimping machine. When feeding, the rated number of counterweight plates need to be counted. However, since the counterweight plates are generally stacked together and are made of metal, the upper and lower counterweight plates fit tightly together and are not easy to grab, so they need to be sliced ​​and divided into individual pieces for processing.

[0003] When the existing counterweight sheet feeding equipment for mold frames is in use, each process needs to be driven separately by a drive device during the automatic feeding of the counterweight sheet and the subsequent sheet separation process. Therefore, multiple drive devices are generally required for control and driving, which makes the overall operation cumbersome and greatly increases the cost. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: when the existing counterweight sheet feeding equipment for the mold frame is in use, during the automatic feeding of the counterweight sheet and the subsequent sheet separation process, each process needs to be driven separately by a driving device, so generally multiple driving devices are required for control and driving, which makes the overall operation cumbersome and greatly increases the cost.

[0006] Preferably, the limiting device includes a plurality of fixed rods, and the plurality of fixed rods are fixedly connected to the support plate, and a baffle is fixedly connected to the fixed rod. The storage table is fixedly connected to a plurality of connecting rings, and the plurality of connecting rings are respectively slidably connected to the outer side walls of the plurality of fixed rods, and an auxiliary supporting device is provided on the base.

[0007] Preferably, the auxiliary support device includes a fixed shaft, the fixed shaft is fixedly connected to the base, the support plate and the storage table are both provided with a circular empty groove, the fixed shaft is arranged opposite to the center of the empty groove, the fixed shaft is fixedly connected to the fixed shaft, and the limit rod is rotatably connected to the support rod, the support rod is symmetrically provided with two top rods, one end of the top rod is provided with a sliding groove, and two L-shaped rods are symmetrically fixedly connected to the outer wall of the support rod, one end of the two L-shaped rods is fixedly connected to the base, the L-shaped rod is slidably connected to the sliding groove, and the outer wall of the support rod is provided with two sections of threads with opposite rotation directions, and a threaded ring is respectively threadedly connected to the two sections of the threads, the threaded ring and the top rod are both fixedly connected to the mounting plate, the mounting plate is fixedly connected to the rotating shaft, and a connecting rod is rotatably connected between the two rotating shafts.

[0008] Preferably, a hexagonal screw block is provided on one end of the support rod away from the base, and the height of the upper end surface of the storage table is level with the height of the top end of the support rod.

[0009] Preferably, a notch is provided on the circumferential side wall of the second gear, and the notch occupies half of the circumferential side wall of the second gear.

[0010] Preferably, the slicing plates are made of stainless steel.

[0011] Preferably, the push rod is cylindrical.

[0012] The beneficial effects of the present invention are: 1. During the entire slicing operation, the driving motor can drive the first gear and the third gear to rotate in turn by virtue of the meshing connection between the second gear and the first gear and the meshing connection between the second gear and the third gear, thereby meeting the needs of the slicing operation process and completing the two processes of switching the workstations and pushing the weight plate to slice in turn. The two processes are completed continuously and in sequence without the need for additional control, which simplifies the overall operation, saves a lot of time, and thus improves work efficiency. In addition, the main power is provided by only one driving motor, saving a lot of cost.

[0013] 2. Place the stacked counterweights on the storage table away from the side of the separation plate. Under the gravity of the counterweights, the storage table overcomes the elastic force of the feeding spring and moves downward. During the up and down movement of the storage table, the fixed rod limits the connecting ring to prevent the storage table from shifting and tilting with the stacked counterweights, thereby ensuring the normal feeding and separation work.

[0014] 3. Rotate the support rod. The support rod drives the two threaded rings away from each other through the two sections of threads with opposite rotation directions on the outer wall. The threaded ring, through the connecting rod structure composed of the mounting plate, the rotating shaft and the connecting rod between the threaded ring and the push rod, cooperates with the limiting effect of the L-shaped rod on the slide groove, to drive the two push rods away from the support rod synchronously until the two push rods are against the inner ring side wall of the counterweight plate, thereby limiting and correcting the counterweight plate from the inside.

[0015] 4. Start the driving motor to drive the first gear and the upper connecting seat to rotate. Since only half of the second gear has meshing teeth, every time the driving motor drives the second gear to rotate one circle, the second gear will drive the first gear to rotate half a circle, and then the first gear stops rotating. During the process of the first gear rotating half a circle, the first gear drives the storage table equipped with stacked counterweight plates to rotate to the bottom of the dividing plate through the upper connecting seat and the first hydraulic cylinder. At the same time, the storage table that has completed the separation of the stacked counterweight plates is rotated from the bottom of the dividing plate to the other side, completing the automatic switching of the workstations to replenish the materials of the counterweight plates. The two workstations cyclically perform the feeding work of the stacked counterweight plates, which significantly improves the work efficiency.

[0016] 5. During the slice operation, after completing the single slice of the counterweight plate that is aligned with the slice slot at the top, since the stacked counterweight plates are highly supported by the elastic force of the feeding spring, as the previous counterweight plate leaves, the total weight of the stacked counterweight plates decreases, and the deformation of the feeding spring decreases and rebounds, driving the height of the overall stacked counterweight plates to rise by the thickness of one counterweight plate, so that the next counterweight plate automatically moves up to align with the slice slot, thereby realizing automatic feeding for the slice operation.

[0026] When the present invention is in use, the stacked counterweight plates are first placed on the storage platform 8 away from the side of the dividing plate 27. Under the gravity of the counterweight plates, the storage platform 8 overcomes the elastic force of the feeding spring 7 and moves downward. Since the stacked counterweight plates are of the same model and size, their thickness and weight are the same. Therefore, it is only necessary that the deformation amount of the feeding spring 7 under the gravity of a single counterweight plate is consistent with the thickness of the counterweight plate. After the stacked counterweight plates are placed on the storage platform 8, since the deformation amount of the feeding spring 7 is consistent with the total thickness of the stacked counterweight plates, the height of the topmost counterweight plate is consistent with the height of the upper end surface of the previous storage platform 8. As for how to ensure that the deformation of the feeding spring 7 generated by the gravity of the single counterweight plate is consistent with the thickness of the counterweight plate, it is only necessary to select a spring with a suitable stiffness coefficient. Since the thickness and weight of the single counterweight plate are known, it is easy and convenient to select a suitable feeding spring 7. In the process of the placement table 8 moving up and down, the fixing rod 9 limits the connection ring 11 to prevent the placement table 8 from shifting and tilting with the stacked counterweight plates, thereby ensuring the normal subsequent feeding and slicing work. After the stacked counterweight plates are placed on the storage platform 8, since the height of the top end of the support rod 14 is consistent with the height of the top end of the storage platform 8 at the beginning, the height of the counterweight plate at the top end is consistent with the height of the top end of the support rod 14 at this time. In order to further limit and correct the stacked counterweight plates to prevent them from being positionally offset during the feeding process, which makes it inconvenient to subsequently separate the plates, the support rod 14 can be rotated. The support rod 14 drives the two threaded rings 18 away from each other through two sections of threads on the outer wall with opposite rotation directions. The threaded ring 18 is connected to the top rod 15 through a connecting rod structure composed of a mounting plate 19, a rotating shaft and a connecting rod 20, and cooperates with the L-shaped rod 17 to limit the slide groove 16, so as to drive the two top rods 15 to synchronously move away from the support rod 14 until the two top rods 15 are against the inner ring side wall of the counterweight plate, and the counterweight plate is limited and corrected from the inside; After the counterweight plates are installed, the drive motor 23 is started. The output end of the drive motor 23 drives the first gear 22 and the upper connecting seat 3 to rotate through the second gear 24. The second gear 24 is consistent in size with the first gear 22. Since only half of the second gear 24 has meshing teeth, the second gear 24 will drive the first gear 22 to rotate half a circle every time the drive motor 23 drives the second gear 24 to rotate one circle, and then the first gear 22 stops rotating. During the process of the first gear 22 rotating half a circle, the first gear 22 drives the storage table 8 equipped with the stacked counterweight plates to rotate to the bottom of the dividing plate 27 through the upper connecting seat 3 and the first hydraulic cylinder 5. At the same time, the storage table 8 that has completed the separation of the stacked counterweight plates is rotated from the bottom of the dividing plate 27 to the other side, completing the automatic switching of the workstations so as to replenish the materials of the counterweight plates. The two workstations cyclically perform the feeding work of the stacked counterweight plates, which significantly improves the work efficiency. When the loading platform 8 with the stacked weight plates is rotated to the position directly below the splitting plate 27, the first hydraulic cylinder 5 is started to drive the support plate 6 to move upward by the thickness of one weight plate, so that the top of the support rod 14 is at the same height as the second weight plate from the top of the stack, thereby ensuring that the support rod 14 does not block the splitting of the first weight plate at the top, and the second hydraulic cylinder 26 is started to drive the splitting plate 27 to move downward, so that the splitting groove 28 is aligned with the top weight plate, and then the driving motor 23 drives the second gear 24 to rotate. The third gear 32 and the rotating rod 31 are driven to rotate, and the rotating rod 31 drives the push rod 35 to rotate through the clamping groove 33 and the clamping ring 34. The rotating push rod 35 pushes the top weight plate into the slice groove 28 in the slice plate 27, and then goes out from the other end of the slice plate 27 in the form of a single piece to complete the slice. For the weight plate after the slice, a clamping or receiving structure can be set at the other end of the slice plate 27 to collect the material. In order to facilitate the clamping, the driving motor 23 can also be set to intermittent rotation with a fixed period; During the above-mentioned slicing operation, after the single-piece slicing of the counterweight sheet aligned with the slicing slot 28 at the top is completed, since the stacked counterweight sheets are highly supported by the elastic force of the feeding spring 7, as the previous counterweight sheet leaves, the total weight of the stacked counterweight sheets decreases, and the deformation of the feeding spring 7 decreases and rebounds, driving the height of the overall stacked counterweight sheets to rise by the thickness of one counterweight sheet, so that the next counterweight sheet automatically moves up to align with the slicing slot 28, thereby realizing automatic feeding of the slicing operation; During the entire slicing operation, since the drive motor 23 can drive the first gear 22 and the third gear 32 to rotate in turn with the help of the meshing connection between the second gear 24 and the first gear 22 and the meshing connection between the second gear 24 and the third gear 32, the needs of the slicing operation process are met, and the two processes of switching the workstations and pushing the counterweight plate to slice are completed in turn. The two processes are completed continuously and in sequence without the need for additional control, which simplifies the overall operation, saves a lot of time, and thus improves work efficiency. The main power is provided by only one drive motor 23, saving a lot of cost.
