Description

Technical Field

[0001] This utility model relates to the field of lid opening and locking technology, and in particular to a lid opening and locking device for a material bucket. Background Technology

[0002] In electroplating production lines, material drums are commonly used containers for material storage and transfer. Opening and locking the drum lids is a necessary step in the material loading and unloading process. Material drum lid opening and locking devices are equipment used to automate these processes. Through a drive mechanism, the actuators, such as screwing and clamping components, work with the drum lid to loosen, remove, align, and tighten the lid, replacing manual labor in these tasks.

[0003] However, the existing material bucket opening and locking devices are prone to friction with the bucket lid during use, causing wear on the locking part of the bucket lid and affecting the accuracy of opening and locking. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a material bucket opening and locking device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a material bucket opening and locking device, including a lifting bracket for support and fixation, a motor-driven lifting bucket frame at one end of the lifting bracket, a material bucket for storing materials inside the lifting bucket frame, and a PLC control system for automated control connected to the lifting bucket frame. A lid opening and locking bracket for support and fixation is fixedly installed in the middle of the lifting bracket, and a drive support controlled by the PLC control system is fixedly installed inside the lid opening and locking bracket. A transfer drive frame controlled by the PLC control system is fixedly installed at one end of the drive support, and a lid opening and locking rod seat for rotational adjustment is fixedly installed at one end of the transfer drive frame. A pressing block for squeezing and tightening the material bucket lid is fixedly installed inside the lid opening and locking rod seat.

[0006] Preferably, one end of the lifting bracket is provided with a sliding guide rail for guiding the lifting bucket frame, the inside of the lifting bucket frame is provided with an installation groove for fixing the material bucket, one end of the material bucket is fitted with a bucket lid for sealing, and one end of both the material bucket and the bucket lid is provided with a locking groove for locking.

[0007] The above technical solution is adopted: the sliding guide rail at one end of the lifting bracket (Q235 steel welding) provides guidance for the lifting bucket frame, ensuring that it rises and falls vertically. The mounting groove of the lifting bucket frame is interference-fitted with the material bucket (polyethylene material). The material bucket is driven by a motor (servo motor) to lift and lower, so that the bucket lid and the lid opening and locking rod seat are precisely aligned. The locking groove of the material bucket and the bucket lid are interlocked, providing a mechanical basis for the turning action. The PLC control system controls the lifting start and stop according to the alignment signal (infrared sensor detection) to ensure that the bucket lid is at the optimal operating height.

[0008] Preferably, in any of the above embodiments, the cover opening and locking bracket is internally connected to a guide connecting rod that connects to the drive support, and the cover opening and locking bracket is fixedly installed at one end of the lifting bracket by bolts.

[0009] The above technical solution is adopted: the cover opening and locking bracket (made of carbon steel) is fixed to the lifting bracket by bolts, bearing the load of the drive support. The internal guide connecting rod slides with the drive support, restricting it to move only along the axial direction, avoiding radial shaking during the drive process. The guide rod surface is chrome-plated to reduce the coefficient of friction, ensure smooth movement of the drive support, and provide stable support for subsequent screwing operations.

[0010] Preferably, in any of the above embodiments, the drive support includes a drive cylinder connected to the PLC control system signal and a movable cover opening and locking fixing seat. The drive cylinder is fixedly installed inside the cover opening and locking bracket, and the output end of the drive cylinder is fixedly installed with the cover opening and locking fixing seat, which is fixedly installed with the guide connecting rod.

[0011] The above technical solution is adopted: the drive cylinder is controlled by the PWM signal of the PLC control system. The output shaft pushes the lid opening and locking fixing seat (aluminum alloy material) to move along the guide connecting rod. When the material bucket is raised to the alignment height, the PLC sends a signal to make the drive cylinder extend, which drives the lid opening and locking fixing seat to approach the bucket lid. After the operation is completed, the cylinder retracts and resets. The rigid connection between the fixing seat and the guide rod ensures that the driving force is transmitted without loss and ensures reliable contact between the locking seat and the bucket lid.

[0012] Preferably, in any of the above embodiments, the adapter drive frame includes a rotary cylinder connected to the PLC control system signal, a drive block for transmitting power, and an adjusting rod for rotational connection. The rotary cylinder is fixedly installed at one end of the cover opening and locking fixing seat, and the output end of the rotary cylinder is fixedly installed with a drive block that moves inside the cover opening and locking fixing seat. The drive block is rotatably connected to the adjusting rod located inside the cover opening and locking fixing seat.

[0013] The above technical solution is adopted as follows: After receiving the PLC command, the rotary cylinder drives the drive block to slide in the cover opening and locking fixing seat. The drive block drives the adjusting rod to rotate through the hinge structure (pin connection), converting linear motion into rotational motion. The adjusting rod and the rotating rod are interference-fitted to ensure torque transmission without slippage, realizing the switching of cover opening / locking screwing action. The PLC controls the rotation direction of the cylinder according to the operation type (cover opening / locking) and automatically resets after the action is completed.

[0014] Preferably, in any of the above embodiments, the lid opening and locking lever seat includes a rotating rod for transmitting power and a locking seat for locking the lid. The rotating rod is rotatably connected inside the lid opening and locking fixing seat. The rotating rod and the adjusting rod are interference-fitted. One end of the rotating rod is fixedly installed with a locking seat that engages with the lid.

[0015] The above technical solution is adopted: the rotating rod rotates inside the lid opening and locking fixing seat, and the locking seat (nylon material) at one end of the rod engages with the locking groove of the lid. When the adjusting rod rotates, the rotating rod drives the locking seat to rotate synchronously. The lid can be loosened (opened) or tightened (locked) through the threaded engagement. The surface of the locking seat is provided with anti-slip texture to increase the friction with the lid and prevent slippage during screwing, thus ensuring reliable operation.

[0016] Preferably, in any of the above embodiments, the pressing block includes a high-strength spring that provides power and a fastening block that presses the lid. The high-strength spring is fixedly installed inside the rotating rod, and one end of the high-strength spring is fixedly installed with a fastening block that moves inside the rotating rod.

[0017] The above technical solution is adopted: a high-strength spring is fixed inside the rotating rod. In the natural state, it pushes the fastening block (polyurethane material) out of the rotating rod. When the locking seat contacts the bucket lid, the fastening block is compressed and the spring generates elastic pressure, so that the fastening block fits tightly against the surface of the bucket lid. This structure can compensate for the alignment error between the locking seat and the bucket lid, reduce the friction and wear caused by hard contact, and at the same time reduce the impact of twisting through elastic buffering, thus extending the service life of the components.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. The device is equipped with a drive mechanism that enables the lid opening and locking lever to engage with the lid of the material container. The engagement and rotation of the lid and lever allow for opening or locking of the container. Simultaneously, a flexible pressing block inside the lever engages with the lid, providing cushioning and protection for the engagement. This reduces friction between the lever and lid, enhancing the accuracy of the device.

[0020] 2. The opening and locking levers are moved by the drive support. Combined with the elastic deformation of the pressing block, each opening and locking lever has a certain margin of movement, which improves the stability of the opening and locking levers in the engagement of the lid and facilitates the stable operation of the opening and locking mechanism.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The internal guide connecting rod 10 slides with the drive support 5, restricting it to move only along the axial direction, avoiding radial shaking during the drive process. The guide rod surface is chrome-plated to reduce the coefficient of friction, ensure smooth movement of the drive support, and provide stable support for subsequent screwing operations.

[0034] Preferably, in any of the above schemes, the drive support 5 includes a drive cylinder 51 connected to the PLC control system signal and a cover opening and locking fixing seat 52 for movement. The drive cylinder 51 is fixedly installed inside the cover opening and locking bracket 4, and the cover opening and locking fixing seat 52, which is fixedly installed with the guide connecting rod 10, is fixedly installed at the output end of the drive cylinder 51.

[0035] The above technical solution is adopted: the drive cylinder 51 is controlled by the PWM signal of the PLC control system. The output shaft pushes the lid opening and locking fixing seat 52 (aluminum alloy material) to move along the guide connecting rod 10. When the material bucket 3 is raised to the alignment height, the PLC sends a signal to make the drive cylinder extend, which drives the lid opening and locking fixing seat 52 to approach the bucket lid 9. After the operation is completed, the cylinder retracts and resets. The rigid connection between the fixing seat and the guide rod ensures that the driving force is transmitted without loss, and ensures reliable contact between the locking seat 72 and the bucket lid.

[0036] Preferably, in any of the above solutions, the transfer drive frame 6 includes a rotary cylinder 61 connected to the PLC control system signal, a drive block 62 for transmitting power, and an adjusting rod 63 for rotational connection.

[0037] Using the above technical solution: After receiving the PLC command, the rotary cylinder 61 drives the drive block 62 to slide in the cover opening and locking fixing seat 52. The drive block drives the adjusting rod 63 to rotate through the hinge structure (pin connection), converting linear motion into rotational motion. The adjusting rod and the rotating rod 71 are interference-fitted to ensure torque transmission without slippage, realizing the switching of opening / locking cover turning action. The PLC controls the rotation direction of the cylinder according to the operation type (opening / locking cover) and automatically resets after the action is completed.

[0038] Preferably, in any of the above embodiments, the lid opening and locking lever seat 7 includes a rotating rod 71 for transmitting power and a locking seat 72 for locking the lid 9.

[0042] The working principle of the material bucket opening and locking device of this utility model is as follows:

Fastening block 82 of pressing block 8 is squeezed, and high-strength spring 81 deforms to provide buffer. After locking, rotating cylinder continues to drive, realizing loosening or tightening of bucket lid 9. After completion, all parts are reset.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] 1. The device is configured to engage with the lid 9 of the material container 3 via a drive mechanism 6.
