Description

Technical Field

[0001] This application relates to the technical field of batching bins, and particularly relates to a device for calibrating the weighing of a batching bin during material discharging and running the tray. Background Art

[0002] The batching bin is an important part of the production line, used to store and supply a large amount of raw material powders or granular materials to ensure the continuity and stability of production; currently, due to various reasons such as limited site and multiple belt transfers of materials, the accuracy of material discharging from the batching bin cannot achieve accurate physical verification. Therefore, it is necessary to calculate whether the weight of the discharged material is consistent with the set material weight. In the prior art, the measurement methods adopted in the production workshop are all realized by manually placing and receiving trays. This method is relatively dangerous near the running belt, and it is easy for workers to be injured by the running belt conveyor, posing a safety hazard. In addition, during the process of receiving materials, the materials continuously impact the surface of the receiving tray, which is likely to cause the worker to lose hold of the tray. If the worker fails to catch the receiving tray, the receiving tray will fall, resulting in the receiving tray jamming the belt and damaging the equipment. Therefore, it needs to be improved. Summary of the Utility Model

[0003] In order to improve the problems of inconvenient operation and potential safety hazards when manually placing and receiving trays for the materials discharged from the batching bin, this application provides a device for calibrating the weighing of a batching bin during material discharging and running the tray.

[0004] A device for calibrating the weighing of a batching bin during material discharging and running the tray provided by this application adopts the following technical solutions:

[0005] A device for calibrating the weighing of a batching bin during material discharging and running the tray includes a frame arranged below the discharging opening of the batching bin. A belt conveyor is arranged inside the frame. Two parallel tracks are arranged above the belt conveyor. A receiving tray for receiving materials is slidably connected to the tracks, and the bottom wall of the receiving tray abuts against the surface of the belt conveyor.

[0006] By adopting the above technical solutions, during the operation of the belt conveyor, since the bottom wall of the receiving tray is in contact with the surface of the belt conveyor, the belt conveyor can drive the receiving tray to move. When the receiving tray moves below the discharging opening of the batching bin, it can receive the materials discharged from the discharging opening of the batching bin. This application enables no need for direct manual operation when running the tray for weighing calibration, avoiding the potential hazard of equipment operation causing harm to the human body, and also avoiding the problem of equipment jamming and damage caused by the receiving tray dropping due to failure to catch. It improves the safety during the production process.

[0007] Optionally, a plurality of rollers are arranged on the side wall of the receiving tray close to the track, and the rollers are slidably connected to the track.

[0008] By adopting the above technical solution, setting up the roller can effectively reduce the resistance received by the receiving tray when sliding along the belt conveyor, making the operation of the receiving tray more sensitive and reducing wear, thereby effectively improving the service life of the entire device.

[0009] Optionally, two sets of winches are provided above the frame, and the two winches are distributed along the length direction of the rail. Each winch is provided with two chains, and the chains and rails are provided in a one-to-one correspondence, and the other end of the chain is connected to the corresponding rail.

[0010] By adopting the above technical solution, a winch and a chain are set up so that the rails can be raised and lowered, thereby facilitating the adjustment of the position of the receiving tray relative to the belt conveyor, so that the belt conveyor can more easily drive the receiving tray to run on the belt conveyor, thereby improving the flexibility and applicability of the calibration device of this application.

[0011] Optionally, when the chain is completely unwound, the rail has no contact with the surface of the belt conveyor.

[0012] By adopting the above technical solution, it is possible to prevent the rails from dropping too low, which would cause the rails to collide with the belt conveyor, and then cause the belt conveyor to get stuck and be unable to operate normally. This improves the safety of the operation of the calibration device of this application and extends the overall service life of the equipment.

[0013] Optionally, limit blocks are provided at both ends of the rail.

[0014] By adopting the above technical solution, setting limit blocks at both ends of the rail can effectively prevent the receiving tray from sliding out of the rail, thereby ensuring the stability and safety of the operation of the calibration device of this application.

[0015] Optionally, the inner diameter of the discharging port of the batching bin gradually decreases from top to bottom.

[0016] By adopting the above technical solution, the material discharge from the discharge port of the batching bin can be made more concentrated, which facilitates more accurate material collection and improves the accuracy of subsequent calibration.

[0017] Optionally, the surface size of the receiving tray is larger than the size of the bottom opening of the material discharging port of the material bunker.

[0018] By adopting the above technical solution, the surface size of the receiving tray is larger than the opening size at the bottom of the discharging port of the material bin, so that all the materials in the cross-section can be received in the receiving tray, thereby preventing the materials from scattering, causing the weighing results to be inconsistent with the actual discharge weight, and affecting the accuracy of the calibration.

[0019] Optionally, the rail is arranged parallel to the belt conveyor.

[0020] By adopting the above technical solution, the rail is arranged parallel to the belt conveyor, so that the belt conveyor can drive the material receiving tray to move stably along the direction of the belt conveyor during operation, thereby accurately receiving the material coming out of the discharge opening of the batching bin, preventing the scattering of the material, and improving the accuracy and efficiency of subsequent weighing calibration.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the running tray weighing calibration is required in the present application, there is no need for manual direct operation, which avoids the potential hazard of equipment operation causing harm to the human body, and also avoids the problem of equipment jamming and damage caused by the material receiving tray not being caught and falling, improving the safety during the production process;

[0023] 2. The setting of the winch and the chain enables the rail to be lifted and lowered, so as to facilitate the adjustment of the position of the material receiving tray relative to the belt conveyor, enabling the belt conveyor to drive the material receiving tray to run on the belt conveyor more easily, and improving the flexibility and applicability of the weighing calibration device of the present application;

[0024] 3. The setting of the limit blocks at both ends of the rail can effectively prevent the material receiving tray from sliding out of the rail, thus ensuring the stability and safety of the operation of the weighing calibration device of the present application.

[0028] The following will further describe the present application in detail Figure 1-2 in conjunction with the attached

[0029] The embodiment of the present application discloses a batching bin discharging running tray weighing calibration device. Referring to Figure 1 , including the discharge opening 1 of the batching bin. In this embodiment, the inner diameter of the discharge opening 1 of the batching bin gradually decreases from top to bottom, so that the discharging can be more concentrated and the scattering of the material can be reduced.

[0030] Referring to Figure 1The lifting of the lifting device is to lift the lifting device 1 and lower the lifting device 10, so that the lifting device 10 can be lifted off the lifting device 10, 10, and 20 miles of landline 4 can be used for lifting the lifting device 10.

[0031] Reference Figure 1 Two sets of winches 7 are provided on the frame 2, and the two sets of winches 7 are distributed along the length direction of the rail 4. The two sets of winches 7 are respectively provided at the two ends of the rail 4, and each winch 7 is provided with two sets of chains 8, wherein the chains 8 and the rail 4 are provided in a one-to-one correspondence, and the other ends of the chains 8 are connected to the surface of the corresponding rail 4 to drive the rail 4 to rise and fall, and then adjust the distance between the bottom wall of the receiving tray 5 and the surface of the belt conveyor 3, so that the belt conveyor 3 can fully drive the receiving tray 5 to slide, so as to ensure the flexibility and convenience of the device when the material needs to be calibrated; in this embodiment, when the chain 8 is fully unwound, the rail 4 cannot come into contact with the belt conveyor 3, thereby preventing the rail 4 from falling too low, causing the rail 4 to collide with the belt conveyor 3, and then causing damage to the belt conveyor 3.

[0032] Reference Figure 1 , both ends of the rail 4 are provided with limit stops 9 by welding, the length direction of the limit stops 9 is perpendicular to the length direction of the rail 4, and the two ends of the limit stops 9 are respectively welded to the surface of the two rails 4 to improve the connection stability. The setting of the limit stops 9 can prevent the receiving tray 5 from leaving the rail 4 due to excessive sliding, thereby improving the stability and safety of the calibration device of the present application during use.

[0033] The implementation principle of the device for calibrating the material running disc of a batching bin in an embodiment of the present application is as follows: when the material needs to be calibrated, the rail 4 and the receiving disc 5 are adjusted by the winch 7 and the chain 8, so that during the operation of the belt conveyor 3, the bottom wall of the receiving disc 5 fits with the surface of the belt conveyor 3, and the belt conveyor 3 can drive the receiving disc 5 to move. When the receiving disc 5 moves to the bottom of the material discharge port 1 of the batching bin, it can receive the material discharged from the material discharge port 1 of the batching bin. The present application makes it possible to operate the running disc directly without manual operation when it is needed, thereby avoiding the hidden danger of harm to the human body caused by the operation of the equipment, and also avoiding the problem of the equipment being stuck and damaged due to the receiving disc 5 not being caught and falling, thereby improving the safety of the production process.
