Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a material hoisting mechanism with cutting function. Background Technology

[0002] A winch mechanism is a mechanical device used to lift or pull heavy objects. It achieves vertical lifting, horizontal or inclined pulling by winding a steel wire rope or chain around a drum. Its core components include an electric motor, a reducer, a drum, a brake, and a steel wire rope. The electric motor provides power, which is reduced in speed and increased in torque by the reducer to drive the drum to rotate. The drum moves the heavy object by winding the steel wire rope, while the brake ensures safe operation.

[0003] In the existing technology, general material hoisting mechanisms usually do not have cutting functions. The hoist is only responsible for unwinding and feeding the material, and cutting needs to be completed by downstream equipment. The material needs to go through multiple turnovers and wait. Therefore, it is necessary to improve the material hoisting mechanism with cutting function to solve the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a material hoisting mechanism with a cutting function, comprising a hoisting section, a cutting section on one side of the hoisting section, a frame 1, a hoisting roller 11 rotatably connected to the frame 1, a stepper motor 12 for driving the hoisting roller 11 to rotate on the frame 1, a sprocket 1 mounted on the output end of the stepper motor 12, a sprocket 4 coaxially mounted on one side of the hoisting roller 11, a sprocket 2 and a sprocket 3 coaxially mounted between the sprocket 1 and the sprocket 4, the axes of the sprocket 2 and the sprocket 3 being parallel to the axes of the sprocket 1 and the sprocket 4, a second chain 132 meshing with the sprocket 1 and the sprocket 2, and a first chain 131 meshing with the sprocket 3 and the sprocket 4, the sprocket 1 being synchronized with the stepper motor 12. The rotating mechanism includes sprockets 2 and 3 rotating synchronously, and sprocket 4 rotating synchronously with the winch roller 11. Sprockets 3 and 4 are connected to a rotating shaft 31. A cutting part is fixed at the outer diameter of the rotating shaft 31. The cutting part includes a turntable 32. A post 321 is provided on one side of the turntable 32 along its axial direction. A cutting blade 33 is attached to the side of the turntable 32 with the post 321. The cutting blade 33 has a shaft hole 331 corresponding to the post 321. A stepper motor 12 drives the winch roller 11 to wind and unwind while simultaneously rotating the turntable 32 together, saving manufacturing costs. The post 321 can be inserted into the shaft hole 331, which facilitates the rotation adjustment of the cutting blade 33 and the adjustment of the cutting range of the cutting blade 33, enabling the cutting of tape seals on cartons of different heights.

[0023] Please see Figure 1 - Figure 4In this embodiment, a base frame 21 is provided below the rotating shaft 31, located on the left side of the frame 1. A vertically upward side plate 22 is welded to the left side of the base frame 21. The left side of the rotating shaft 31 can be inserted into the side plate 22 for rotation. By inserting the left side of the rotating shaft 31 into the side plate 22, a rotational connection at one end of the rotating shaft 31 is achieved, increasing the stability of the rotating shaft 31's operation. The turntable 32 is provided with screw holes 322 arranged in a ring around the insertion post 321. The cutting blade 33 is provided with an adjustment hole 332 corresponding to the screw holes 322. A screw can pass through the adjustment hole 332 and engage with the screw holes 322. The screw holes 322 facilitate the fixing of the cutting blade 33, reducing the cutting blade 33's resistance to cutting. The offset is adjusted so that the adjustment hole 332 can correspond to the screw hole 322 to achieve adjustment of multiple positions. A fixing block 43 is welded to the top of the bottom frame 21. A driven roller 42 is rotatably connected between the side plate 22 and the fixing block 43. The driven roller 42 is located below the rotating shaft 31. There are no fewer than two driven rollers 42. The driven rollers 42 are arranged linearly in the front-back direction. A limiting shaft 41 is inserted into the driven roller 42. One end of the limiting shaft 41 is located on the left side of the side plate 22, and the other end of the limiting shaft 41 is located on the right side of the fixing block 43. Through the cooperation of the side plate 22 and the fixing block 43, the driven roller 42 can be rotated and connected to realize the carrying capacity of the cardboard box by the driven roller 42, and can be easily pushed.

[0024] Please see Figure 2 - Figure 5 In this embodiment, an adjusting block 443 is slidably connected to the bottom of the bottom frame 21. The top of the adjusting block 443 is provided with an extension block 442 that avoids the driven roller 42. A limit baffle 441 is connected to the left side of the extension block 442. The limit baffle 441 is located above the driven roller 42. The limit baffle 441 can limit the direction of the carton rolling on the driven roller 42 and reduce the occurrence of deviation. The front and rear ends of the adjusting block 443 are respectively provided with screw holes 4430. The bottom frame 21 is provided with an adjusting groove corresponding to the position of the screw holes 4430. 210, the length direction of the adjusting groove 210 points to the left and right ends. The adjustment range of the adjusting block 443 is realized by adjusting the adjusting groove 210, so that the limiting baffle 441 can fit various sizes of cardboard boxes. A rope 110 is wound on the hoisting roller 11. A cover 23 is provided on the side plate 22 and the frame 1. The rope 110 wound on the hoisting roller 11 can pull the cardboard box close to the hoisting roller 11. The cover 23 can prevent debris from accidentally falling and hitting the cutting blade 33, and can also protect the operator to a certain extent.

[0025] During operation, the material referred to here is a cardboard box. Stepper motor 12 is electrically driven to rotate sprocket one. Sprocket one, through the second chain 132, drives sprocket two to rotate. Because sprocket two and sprocket three are both fixed on the rotating shaft 31, they rotate simultaneously. Sprocket three, through the first chain 131, drives sprocket four to rotate, which in turn drives the hoisting roller 11 to rotate. When the hoisting roller 11 retracts the rope 110, it can pull the cardboard box material closer to the mechanism body. After the manual person retrieves the cardboard box, it is placed above the driven roller 42, and a stick is used to push the cardboard box forward. The rotation of the rotating shaft 31 also drives the turntable 32 to rotate, which in turn drives the cutting blade 33 to perform a circular motion. The cutting blade 33 can... The cutting blade 33 can cut the seal on the cardboard box. When it is necessary to adjust the cutting range of the cutting blade 33, rotate the cutting blade 33 around the axis of the insert post 321, align the adjusting hole 332 with the appropriate screw hole 322, and then tighten the screw. The cutting blade 33 can cut the seal on the cardboard box of three different heights. In order to prevent the cardboard box from running off course when it is pushed on the driven roller 42, the screw at the screw hole 4430 can be loosened, the adjusting block 443 can be pushed until the limit baffle 441 fits against the side wall of the cardboard box, and then the screw at the screw hole 4430 can be tightened again. When adjusting this mechanism, the stepper motor 12 needs to be disconnected from the power supply to avoid injury. The stepper motor 12 is existing technology, and its working principle will not be described in detail here.

[0026] Through the above steps, a stepper motor 12 drives the winch roller 11 to wind and unwind, while simultaneously rotating the turntable 32, saving on the manufacturing cost of the device. The shaft hole 331 can be inserted into the insert post 321, which facilitates the rotation adjustment of the cutting blade 33, thereby adjusting the cutting range of the cutting blade 33 and enabling the cutting of tape seals on cartons of different heights. This solves the problem in the existing technology where the material winch mechanism cannot cut on the same mechanism, which takes a lot of time and requires an additional motor to cut the material, increasing the production line manufacturing cost.
