Description

Technical Field

[0001] This utility model relates to the field of material distribution and box unloading technology, specifically a box unloading mechanism based on screw material distribution. Background Technology

[0002] In the production process of some products, containers such as square boxes and round drums are among the most commonly used items. To reduce the volume occupied by these containers, they are usually designed to be stackable for batch storage and management, improving space utilization and work efficiency. However, these containers must be separated before use. That is, they must be separated from their stacked state before use. Therefore, in some scenarios, manual separation may be used, or a container separation device may be employed. Especially in scenarios requiring frequent stacking and separation, such as warehouses, security checks, and logistics, automated container separation devices are essential equipment for improving efficiency.

[0003] Utility model patent CN212923555U discloses a box-separating device, including a screw, a frame, and a drive assembly. The screw is rotatably fixed to the frame, and the drive assembly is connected to the frame. The drive assembly is configured to drive the screw to rotate around a shaft. The screw surface is provided with unequal-pitch threads. The ribs of the stacked boxes contact the threads, and the boxes are separated under the force of the threads. The device also includes a conveying mechanism, which is mounted on a first support plate and configured to transport the separated boxes away from the box-separating device. This utility model has advantages such as low site dependence, simple structure, high box-separating efficiency, and low manufacturing cost.

[0004] However, in common box-and-cylinder separation and unloading mechanisms, the height of the unloading port is fixed during use, which requires a certain height for the output conveyor belt. The installation height needs to be adjusted for different usage scenarios, and the height also needs to be adjusted when the specifications of the box and cylinder change. The adjustment process is quite troublesome. Therefore, a screw-based unloading mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screw-based material distribution box mechanism, which has advantages such as convenient adjustment of the material discharge port height, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A screw-based material distribution box lowering mechanism includes an installation platform, an adjustable box assembly on the top of the installation platform, four bearing seats fixedly installed on the bottom of the installation platform, a material distribution screw rotatably installed on the bottom of the bearing seats, a drive mechanism for driving the material distribution screw to rotate on the top of the installation platform, and a height adjustment assembly on the top of the installation platform.

[0008] The height adjustment assembly includes four sliding bearings fixedly installed on the top of the installation platform. A lifting guide rail is slidably installed inside the sliding bearings. A support base is fixedly installed at the bottom end of the lifting guide rail. An installation top plate is fixedly installed at the top of the lifting guide rail. A fixing nut is fixedly installed on the top of the installation platform. A lifting screw is threadedly connected inside the fixing nut. The top end of the lifting screw is rotatably connected to the installation top plate. A lifting rocker is rotatably installed on the top of the installation top plate. The rotation shaft of the lifting rocker is fixedly connected to the top end of the lifting screw.

[0009] Furthermore, the adjustable compartment assembly includes four mounting rails fixedly installed on the top of the mounting platform, a movable base plate is slidably installed inside the mounting rails, and two compartment stops are fixedly installed on the top of the movable base plate.

[0010] Furthermore, the top of the installation platform is provided with a discharge port, and the movable base plate is located at the top of the four sides of the discharge port. A reinforcing support rod is fixedly installed on the top of the movable base plate, and a reinforcing support plate is fixedly installed at the top of the reinforcing support rod. One side of the reinforcing support plate is in contact with the box compartment stop bar.

[0011] Furthermore, the drive mechanism includes four driven synchronous pulleys rotatably mounted on the top of the mounting platform, a drive synchronous pulley rotatably mounted on the top of the mounting platform, two guide pulleys rotatably mounted on the top of the mounting platform, and a servo motor fixedly mounted on the bottom of the mounting platform, with the output shaft of the servo motor fixedly connected to the drive synchronous pulley.

[0012] Furthermore, the surfaces of the four driven synchronous pulleys and the driving synchronous pulley are provided with synchronous belts, the two guide pulleys are located on the outside of the synchronous belts, and the driven synchronous pulleys are fixedly connected to the feed screw.

[0013] Furthermore, two side baffles are fixedly installed on the top of the installation platform, and four positioning mounting rods are fixedly installed on the bottom of the installation platform.

[0014] Furthermore, a positioning pin is provided on one side of each of the four positioning mounting rods, and the positioning pin is adapted to the material distribution screw.

[0015] Compared with the prior art, this utility model provides a screw-based material distribution box lowering mechanism, which has the following beneficial effects:

[0016] 1. This screw-based unloading mechanism uses four sliding bearings on the top of the mounting platform. Lifting guide rails are slidably installed inside the bearings, allowing the mounting platform to slide up and down on the guide rail surface. A lifting rocker drive the lifting screw to rotate, and with the help of a fixing nut, the height of the mounting platform is adjusted. This adapts to conveyor belts of different heights and to square boxes and cylinders of different specifications. It solves the problem of common separate unloading mechanisms for square boxes and cylinders where the unloading port height is fixed, requiring adjustments to the output conveyor belt height, and necessitating height adjustments for different usage scenarios. Furthermore, changes in the size of the square boxes and cylinders also necessitate height adjustments, making the adjustment process cumbersome.

[0017] 2. This screw-based material distribution box lowering mechanism can match different specifications of square boxes and round barrels by adjusting the position of the movable base plate on the mounting slide rail and adjusting the position of the box compartment stop bar. Different specifications of square boxes and round barrels can be matched by changing different material distribution screws, making it convenient to change square boxes and round barrels of different specifications.
