Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment technology, specifically to a lifting mechanism on a lifting and stacking device. Background Technology

[0002] Cardboard boxes, as an important material in the packaging industry, are widely used in the packaging and transportation sector due to their advantages such as durability, ease of processing, low cost, recyclability, and environmental friendliness. In the cardboard box production process, how to stack cardboard boxes orderly and stably to facilitate subsequent packaging, transportation, and storage has always been a crucial issue in the cardboard box manufacturing industry.

[0003] Among the known carton stacking devices, one can refer to the automatic stacking paper receiving device disclosed in Chinese Utility Model Patent Application No. 201420720859.5. In this device, the conveying end of the conveying device is connected to the carton stacking device, which is mounted vertically on a support. Therefore, when the carton stacking device is adjusted up and down on the support, the conveying device needs to extend and retract to match the height change of the carton stacking device. During this process, the length and tension of the conveyor belt will be affected. For example, when the carton stacking device rises, the conveying device extends and the conveyor belt is tightened; when the carton stacking device descends, the conveying device shortens and the conveyor belt becomes loose. Therefore, this not only affects the service life of the conveyor belt, but also makes the cooperation between the conveyor belt and the rotating shaft unstable, resulting in conveying interruption and affecting the normal conveying of cartons. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a lifting mechanism for a stacking device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A lifting mechanism for a stacking device includes a base, a conveying assembly movably mounted on the base, and a stacking assembly rotatably mounted on the conveying end of the conveying assembly. The base also has a lifting mechanism for lifting the conveying device. The lifting mechanism includes a rocker arm, a lifting arm, a balance bar, and a drive cylinder. One end of the rocker arm is hinged to the base, and the other end is hinged to the input end of the conveying assembly to form a support. One end of the lifting arm is hinged to the top of the base, and the other end is hinged to the middle of the conveying assembly. One end of the balance bar is hinged to the lifting arm near the conveying assembly, and the other end is hinged to the stacking assembly. Both ends of the drive cylinder are hinged between the base and the lifting arm to form a support. The drive cylinder lifts the conveying assembly by driving the lifting arm to rotate. When the lifting arm rotates, the balance bar keeps the stacking assembly in a horizontal state.

[0007] In this invention, a first hinge seat is provided on the base near the input end, and a first connecting plate is provided on the side of the conveying assembly located at the input end. The two ends of the rocker arm are respectively hinged to the first hinge seat and the first connecting plate. A support column extends vertically upward from one end of the base near the end of the conveying process. A second hinge seat is provided at the top of the support column. A second connecting plate is provided on the side of the conveying assembly located in the middle. The two ends of the lifting arm are respectively hinged to the second hinge seat and the second connecting plate. A third hinge seat is provided on the base near the support column, and the two ends of the drive cylinder are respectively hinged to the third hinge seat and the middle of the lifting arm.

[0008] Furthermore, a connecting rod is provided at one end of the lifting arm near the second connecting plate, and one end of the balance bar is hinged to the connecting rod. The connecting rod and the balance bar form a four-bar linkage with the conveying assembly and the stacking assembly.

[0009] Furthermore, the balance bar includes two identical connecting rods that are telescopically connected.

[0010] In this utility model, the conveying assembly includes two parallel lifting platforms, a rotating shaft rotatably mounted at both ends of the lifting platforms, multiple pulleys spaced apart on the rotating shafts, multiple conveyor belts sleeved on the pulleys at both ends, and a drive motor mounted on the lifting platforms. The drive motor is connected to the rotating shafts and drives the pulleys to rotate synchronously.

[0011] Furthermore, the conveying end of the conveying assembly is also provided with multiple pressure roller assemblies. The multiple pressure roller assemblies are installed on a pressure roller shaft that spans above the conveying assembly. The two ends of the pressure roller shaft are fixedly connected to the lifting platform on both sides by brackets. The multiple pressure roller assemblies are sequentially pressed against the ends of multiple conveyor belts. The pressure roller assembly includes a telescopically adjustable pressure roller bracket and a pressure roller rotatably installed at the end of the pressure roller bracket. The end of the pressure roller bracket away from the pressure roller is rotatably installed on the pressure roller shaft. When the carton is output, the pressure roller is pressed against the carton by its own weight.

[0012] In this utility model, the stacking assembly includes two mounting plates rotatably mounted on the conveying end of the lifting platform. The two mounting plates are symmetrically arranged. It also includes two side baffles and a rear baffle installed between the two mounting plates. When the carton is output, the two side baffles limit the two sides of the carton respectively, and the rear baffle limits the rear side of the carton.

[0013] Furthermore, the mounting plates on both sides are connected and fixed by a crossbeam, and an adjusting rod is also provided between the mounting plates on both sides. The two side baffles are movably mounted on the adjusting rod, and the rear baffle is movably mounted on the mounting plate through a connecting frame.

[0014] This utility model has the following advantages and beneficial effects:

[0015] A lifting assembly is installed on the base. The lifting assembly is hinged between the base and the conveying assembly via a lifting arm, and between the lifting arm and the stacking assembly via a balance bar. The driving cylinder drives the lifting arm to rotate, thereby lifting the conveying assembly. During the rotation of the lifting arm, the balance bar keeps the stacking assembly in a horizontal position. This lifting mechanism can lift both the conveying assembly and the stacking assembly simultaneously, and it does not require the conveying assembly to extend or retract during the lifting process. It can also keep the stacking assembly in a horizontal position, thus facilitating the stacking of cartons. Attached Figure Description

The base 1 is further provided with a lifting mechanism 2 for lifting the conveying device. The lifting mechanism 2 includes a rocker arm 21, a lifting arm 22, a balance bar 23, and a drive cylinder 24. One end of the rocker arm 21 is hinged to the base 1, and the other end is hinged to the input end of the conveying assembly 3 to form a support.

The two ends of the driving cylinder 24 are hinged between the base 1 and the lifting arm 22 to form a support. The driving cylinder 24 lifts the conveying component 3 by driving the lifting arm 22 to rotate. During the rotation of the lifting arm 22, the stacking component 4 is kept horizontal by the balance bar 23. The lifting mechanism 2 with this structure can not only lift the conveying component 3 and the stacking component 4 at the same time, but also does not need to extend or retract the conveying component 3 during the lifting process, and can keep the stacking component 4 horizontal at the same time, thus facilitating the stacking of cartons.

[0024] In this embodiment, a first hinge seat 11 is provided at one end of the base 1 near the input end, and a first connecting plate 300 is provided on the side of the conveying assembly 3 at the input end. The two ends of the rocker arm 21 are respectively hinged to the first hinge seat 11 and the first connecting plate 300. A support column 10 extends vertically upward from one end of the base 1 near the end of the conveying process. A second hinge seat 12 is provided at the top of the support column 10. A second connecting plate 301 is provided on the side of the conveying assembly 3 in the middle. The two ends of the lifting arm 22 are respectively hinged to the second hinge seat 12 and the second connecting plate 301. A third hinge seat 13 is provided on the base 1 near the support column 10. The two ends of the drive cylinder 24 are respectively hinged to the third hinge seat 13 and the middle of the lifting arm 22.

[0025] Furthermore, a connecting rod 221 is provided at one end of the lifting arm 22 near the second connecting plate 301, and one end of the balance rod 23 is hinged to the connecting rod 221. At this time, the connecting rod 221 and the balance rod 23 form a four-bar linkage with the conveying assembly 3 and the stacking assembly 4. Therefore, the stacking assembly 4 is kept horizontal during the lifting and lowering process of the conveying assembly 3. Specifically, in order to pre-adjust the installation angle of the stacking assembly 4, the balance rod 23 is composed of two connecting rods 230 with the same structure. The two connecting rods 230 are telescopically connected. The specific connection method of the two connecting rods 230 can be referred to the connection method of the slide rod and the main rod in an automatic stacking paper receiving device mentioned in the background art patent application number 201420720859.5, which will not be elaborated here.

[0026] In this embodiment, the conveying assembly 3 includes two parallel lifting platforms 31, a rotating shaft 32 rotatably mounted at both ends of the lifting platform 31, a plurality of pulleys 33 spaced apart on the rotating shaft 32, a plurality of conveying belts 34 sleeved on the pulleys 33 at both ends, and a drive motor 35 mounted on the lifting platform 31. The drive motor 35 drives the pulleys 33 to rotate synchronously through the rotating shaft 32 at one end.

[0027] Furthermore, the conveying end of the conveying component 3 is also provided with multiple pressure roller assemblies 36. The multiple pressure roller assemblies 36 are mounted on a pressure roller shaft 361 spanning above the conveying component 3. The two ends of the pressure roller shaft 361 are fixedly connected to the lifting platform 31 on both sides by brackets.

Specifically, the pressure roller assembly 36 includes a telescopically adjustable pressure roller bracket 362 and a pressure roller 363 rotatably mounted on the end of the pressure roller bracket 362. The end of the pressure roller bracket 362 away from the pressure roller 363 is rotatably mounted on the pressure roller shaft 361. When the carton is output, the pressure roller 363 presses against the carton by its own weight to keep it stable and improve the stability of the carton output.

[0028] In this embodiment, the stacking assembly 4 includes two mounting plates 41 rotatably mounted on the conveying end of the lifting platform 31. The two mounting plates 41 are symmetrically arranged. It also includes two side baffles 42 and a rear baffle 43 installed between the two mounting plates 41. When the cartons are output, the two side baffles 42 limit the two sides of the cartons respectively, and the rear baffle 43 limits the rear side of the cartons, thereby making the cartons stack neatly. Specifically, the two mounting plates 41 are connected and fixed by a crossbeam 410, and an adjusting rod 411 is also provided between the two mounting plates 41. The two side baffles 42 are movably mounted on the adjusting rod 411, and the rear baffle 43 is movably mounted on the mounting plate 41 through a connecting frame 412.
