Description

Technical Field

[0001] The utility model relates to the technical field of feeding of plate shears, and more specifically, to a feeding mechanism for plate shears. Background Art

[0002] Shearing machine is a machine that shears plates by reciprocating linear motion of one blade relative to another blade. It applies shear force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap, so that the plates are broken and separated according to the required size; however, the existing shearing machine structure does not take into account that excessive plate load will affect the transmission rate, and in severe cases, it will cause excessive wear or even damage to the transmission mechanism.

[0003] The utility model patent with patent publication number CN202021257419.2 discloses a feeding mechanism for a shearing machine, including a bracket, a roller and a power motor; the bracket includes a pillar, a support panel and a roller box, the support panel is located at the lower part of the roller box, the pillar is fixedly connected to the support panel, the pillar is located at the lower part of the roller box, and the pillar is fixedly connected to the roller box; a power motor is provided on the side of the roller box, the power motor is fixedly connected to the roller box, and the power motor is movably connected to the roller, fully taking into account the problem that the plate cannot be lifted and the wear of the conveying mechanism.

[0004] However, when this structure is actually used, since there are no limit components on both sides of the plate to prevent the plate from shifting or other situations during transportation, it is impossible to ensure that the plate will not fall or get stuck due to shifting during transportation. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a feeding mechanism for a shearing machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism for a shearing machine, comprising a supporting panel, a vertical rod is provided inside the supporting panel, a roller box is provided on the top of the vertical rod, a pulley is provided inside the roller box, a processing plate is provided on the top of the pulley, an overload cylinder is provided on the top of the supporting panel, a lifting cylinder is provided on one side of the overload cylinder, and a limit assembly is provided on one side of the roller box.

[0007] Preferably, the limiting assembly includes a connecting plate, which is arranged on one side of the roller box, a limiting plate is provided on the top of the connecting plate, a sliding groove is provided on the surface of the limiting plate, a limiting protrusion is installed on one side of the limiting plate, a rectangular groove is provided on the end face of the limiting plate, a sliding card plate is provided inside the sliding groove, a fixed block is provided at one end of the sliding card plate, a Z-shaped handle is provided inside the fixed block, one end of the Z-shaped handle passes through the fixed block and is adapted to be engaged with the rectangular groove, a return spring is provided on the top surface of one end of the connecting plate, and the sliding card plate is adapted to be engaged with the limiting protrusion.

[0008] Through the above scheme, it can be seen that by installing a connecting plate on the outside of the roller box and fixing one side surface of the connecting plate to the outer surface of the roller box, the limit plate can be stably placed on one end of the roller box, and the staff can manually lift and slide the sliding pallet along the inside of the slide groove according to the actual length of the processing plate, and when the bottom of the sliding pallet is in contact with the top surface of the processing plate, the staff needs to find the square slot closest to the center of the fixed block near the fixed block, and then manually pass the Z-shaped handle through the fixed block and the rectangular slot to achieve the height fixation of the sliding pallet. At this time, the processing plate will not be offset during transportation, thereby improving work efficiency and preventing the processing plate from falling.

[0009] Preferably, the length of the roller box is equal to the length of the connecting plate, the processing plate is movably connected, and one side surface of the connecting plate is fixedly connected to the outer side surface of the roller box.

[0010] Through the above scheme, it can be seen that the length of the connecting plate and the roller box is set to be equal, and then the length of the sliding card plate on one side of the limit plate is also equal to the length of the connecting plate, so the processing plate is always in a stable moving state when moving on the pulley surface.

[0011] Preferably, an electric telescopic rod is provided at the bottom of the support panel, the number of the electric telescopic rod is set to two, and the end surface of the electric telescopic rod is fixedly connected to the bottom surface of the support panel.

[0012] Through the above scheme, it can be seen that by controlling the electric telescopic rod to descend, the supporting panel is driven to descend synchronously, thereby increasing the space on the top of the supporting panel for easy storage.

[0013] Preferably, a support plate is connected to the bottom of the electric telescopic rod, a protective plate is provided on the top surface of the support plate, and the number of the protective plates is set to two.

[0014] Through the above scheme, it can be seen that an electric telescopic rod is installed at the bottom of the support panel, and a support plate is installed at the bottom of the electric telescopic rod. Therefore, when the product is defective or scrapped, the staff can put the recyclable processing plate on the top of the support plate nearby, and the processing plate can also be limited by the protective plates on both sides of the support plate to prevent the processing plate from sliding to the outside of the support plate, thereby improving the practicability of the device. At the same time, when the work is finished, the staff can control the contraction of the electric telescopic rod to lift the support plate upward, which can reduce the footprint of the device and make it easier for the staff to clean the bottom of the device, thereby improving the practicability of the device.

[0015] Preferably, a rotating baffle is provided on one side of the support plate, and the rotating baffle is hingedly connected to the support plate.

[0016] Through the above scheme, it can be seen that by engaging the rotating baffle plate with the protective plate, the position of the processing plate on the top of the support panel can be limited to improve stability.

[0017] Technical effects and advantages of the utility model:

[0018] 1. By setting a limit assembly, compared with the prior art, a connecting plate is installed on the outside of the roller box, and one side surface of the connecting plate is fixedly connected to the outer surface of the roller box, so that the limit plate can be stably placed on one end of the roller box, and the staff can manually lift and slide the sliding card plate along the inside of the slide groove according to the actual length of the processing plate, and when the bottom of the sliding card plate fits the top surface of the processing plate, the staff needs to find the square card slot closest to the center of the fixed block upward near the fixed block, and then manually pass the Z-shaped handle through the fixed block and the rectangular card slot, so as to achieve the height fixation of the sliding card plate. At this time, the processing plate will not be offset during transportation, thereby improving work efficiency and preventing the processing plate from falling;

[0019] 2. By setting a support plate and an electric telescopic rod, compared with the prior art, the electric telescopic rod is installed at the bottom of the support panel, and the support plate is installed at the bottom of the electric telescopic rod. Therefore, when the product is defective or scrapped, the staff can put the recyclable processing plate on the top of the support plate nearby, and the processing plate can also be limited by the protective plates on both sides of the support plate to prevent the processing plate from sliding to the outside of the support plate, thereby improving the practicability of the device. At the same time, when the work is completed, the staff can control the contraction of the electric telescopic rod to lift the support plate upward, which can reduce the footprint of the device and also make it easier for the staff to clean the bottom of the device, thereby improving the practicability of the device.
